Janggi shares some similarities with Chinese chess, or Xiangqi, but it has important differences. The board contains nine vertical lines and ten horizontal lines, and unlike Xiangqi, it does not have a river dividing the board across the middle.
The game combines tactical attacks with longer strategic plans. Cannons can make powerful jumping attacks, elephants have long-range movement, and professional-level games can extend beyond 150 moves.

The current Google Play listing identifies Dr. Janggi as a board, abstract strategy, chess, multiplayer and competitive multiplayer game.
Janggi is a traditional Korean board game derived from the broader family of East Asian chess-like strategy games.
Although it resembles Xiangqi, the rules and board structure are not identical.
The game uses:
The objective is to use these pieces together to place pressure on the opposing general and eventually win the game.
The board is made from nine vertical lines and ten horizontal lines, creating the characteristic 9×10 Janggi layout. Unlike Xiangqi, there is no horizontal river separating the two sides.
This structure affects how pieces interact.
Long-range pieces can exert pressure across large portions of the board, while the palace areas create important tactical zones around the generals.
Learning the geometry of the board is one of the first steps toward becoming comfortable with Janggi.
Understanding each piece is essential before trying advanced tactics.
The general is the most important piece on your side.
Protecting your general should always remain a priority.
At the same time, the general can become an important tactical piece in the palace area during certain positions.
Guards protect the general and operate within the palace structure.
Their restricted movement means they are particularly important for defensive formations.
A common beginner mistake is moving defensive pieces without considering what happens to the general afterward.
The chariot is one of the strongest long-range pieces.
It can move along open lines and can become extremely powerful when files or ranks are clear.
Use chariots to:
Keeping a chariot trapped behind your own pieces can waste much of its potential.
The horse is a tactical piece capable of attacking from unexpected angles.
However, its movement can be affected by blocking pieces.
This means you should always check whether the horse's path is open before planning an attack.
A useful habit is to ask:
What piece is blocking my horse?
Removing that obstruction can suddenly create a tactical threat.
The elephant has unusually long movement compared with many chess pieces.
The Google Play description specifically highlights Janggi's long-range elephants as one reason the game can produce fast tactical sequences.
Elephants can support attacks from a distance and influence areas that beginners may not expect.
Do not overlook an elephant simply because it appears less aggressive than a chariot.
The cannon is one of the defining pieces of Janggi.
Cannons can make powerful jumping attacks, making them particularly dangerous when another piece provides the necessary screen. The official game description specifically mentions jumping cannons as an important feature of Janggi.
Cannon tactics are therefore about more than simply finding an empty line.
You need to consider:
Where is the screen?
and
What piece can the cannon attack beyond it?
Soldiers are more limited than major pieces, but they can become extremely important during the middle and endgame.
Use soldiers to:
Do not automatically sacrifice soldiers simply because they have less mobility.
The opening is about developing useful pieces and creating a position that gives you multiple future options.
Avoid making unnecessary moves with the same piece repeatedly.
Instead, try to:
Chariots become much more effective when their lines are open.
If your own pieces completely block them, you may spend several moves simply trying to activate them.
Look for opportunities to create open files without weakening your position.
Because cannons depend on a screen for their characteristic attack, the position of nearby pieces matters enormously.
A piece that looks passive may actually be enabling a powerful cannon attack.
Before moving a screen piece, check:
Am I accidentally removing my own cannon's tactical opportunity?
Janggi can develop tactical attacks quickly.
Do not focus entirely on attacking pieces while ignoring threats against your own general.
If the opponent's major pieces are becoming active near your palace, defensive preparation may be more important than gaining a small amount of material.
Don't concentrate only on the piece you want to move.
Before every important move, scan:
This prevents many tactical surprises.
Chariots and elephants can influence distant parts of the board.
Before making a move, look across the board for newly opened lines.
A single piece moving away can suddenly expose another piece to attack.
Cannon tactics deserve special attention.
Whenever a cannon is near an opposing piece, identify possible screen pieces.
Ask:
What can the cannon jump over?
Then ask:
What can it attack after the jump?
Trading pieces is not automatically good.
Before exchanging, consider:
A material exchange should have a purpose.
A strong tactical move often creates more than one problem.
For example, a move may:
or:
Multiple threats make defensive responses more difficult.
Cannons deserve special attention because their movement creates tactical patterns that differ from standard chess.
A cannon needs a piece between itself and its target for its characteristic jumping capture.
Therefore, the location of surrounding pieces becomes strategically important.
Before moving a potential screen, check whether:
When multiple cannons coordinate around important lines, they can place substantial pressure on defensive structures.
Try to coordinate them rather than attacking independently.
Chariots thrive on open lines.
Use them to:
Do not move a chariot simply because a square is available.
Ask whether the new position gives it a useful line.
Horses are excellent tactical pieces but require careful planning.
Before moving a horse, examine its possible destinations.
Then determine whether the piece blocking its movement will remain in place.
A horse that cannot access useful squares can become ineffective.
Elephants can influence distant positions and help support attacks.
Because their movement is less familiar to players coming from Western chess, it is easy to underestimate their reach.
When defending, always check whether an enemy elephant can participate in a tactical sequence.
The palace area around the general is one of the most important defensive zones.
When under attack:
A strong palace defense can prevent an otherwise dangerous attack.
Do not attack the opponent's general simply because you have an available move.
A successful attack usually requires preparation.
A useful attacking sequence can involve:
Piece activation → line opening → defensive restriction → tactical threat → attack
Use multiple pieces together.
A single attacking piece can often be driven away, while coordinated pieces can create much greater pressure.
Strong defense begins before the attack becomes dangerous.
When you notice the opponent activating a chariot or cannon toward your palace:
Do not wait until your general is already under severe pressure.
After every significant opponent move, ask:
Did a line open?
Did your piece lose protection?
Can the opponent now use a cannon screen or chariot line?
This final question prevents many blunders.
The middle game is where Janggi becomes particularly tactical.
Your priorities should include:
Avoid making moves simply because they look active.
Every move should improve your position or create a concrete threat.
The endgame often becomes more technical.
When fewer pieces remain:
Do not automatically rush toward the opponent's general.
Calculate whether your remaining pieces can actually support the attack.
Material matters, but the value of a piece depends heavily on its position.
A powerful chariot trapped behind your own pieces may be less useful than a well-positioned horse.
Likewise, a cannon with no useful screen may temporarily have less tactical influence than one positioned near several potential screens.
Think about:
Activity + safety + coordination, not just piece count.
A seemingly harmless move can create a cannon tactic.
Solution: Always inspect cannon lines.
A horse, elephant or chariot can become ineffective when surrounded by friendly pieces.
Solution: Maintain useful movement options.
Launching an attack before your pieces are coordinated can leave them vulnerable.
Solution: Prepare the attack first.
Elephants and chariots can influence distant squares.
Solution: Scan the entire board before important moves.
Defensive pieces can be essential to general safety.
Solution: Consider the consequences before weakening the palace.
Not every exchange improves your position.
Solution: Calculate the resulting position before committing.
Dr. Janggi supports online matches through an internet connection, allowing players to compete against other Janggi players.
Online play requires a different mindset from studying the rules.
You need to make good decisions while managing the pressure of an active opponent.
Before studying advanced openings, become comfortable with every piece.
Cannons are one of the most distinctive tactical elements of Janggi.
Train yourself to scan the entire board after every move.
Instead of asking only why you lost, identify the first important mistake.
If you repeatedly lose because of cannon attacks, focus your practice on cannon screens and defensive positioning.
Before making a tactical move, identify the opponent's strongest response.
Two pieces working together are often more useful than two individually active pieces.
A piece can sometimes serve as a tactical screen for a cannon.
Think about both its defensive and offensive roles.
Opening a line for your chariot can also open a line for your opponent.
When defending, don't simply wait.
A counter-threat can force your opponent to abandon an attack.
Janggi and Western chess share the broad idea of two opposing armies fighting around a royal piece, but their boards and movement systems are substantially different.
| Feature | Janggi | Western Chess |
|---|---|---|
| Board | 9×10 | 8×8 |
| General/King | General | King |
| Cannon | Yes | No |
| Elephant | Janggi elephant | Bishop |
| Chariot | Chariot | Rook |
| Horse | Horse | Knight |
| River | No dividing river | Not applicable |
| Major long-range tactics | Yes | Yes |
| Online play | Supported in Dr. Janggi | Depends on platform |
The comparison is useful for understanding the game's structure, but players should not assume Western chess strategies transfer directly to Janggi.
The basic movement rules can be learned relatively quickly, but strong play requires considerably more practice.
The challenge comes from the interaction between:
The official description notes that professional Janggi games can often last more than 150 moves, showing how much strategic depth the game can contain.
Yes. Google Play currently lists Dr. Janggi with offline functionality as well as multiplayer features.
Online matches require an internet connection.
Yes. The game's Google Play description specifically states that players can sign in and enjoy online matches over the internet.
A Janggi board uses 9 vertical lines and 10 horizontal lines. This produces the distinctive 9×10 board used by the game.
Both games are closely related and share several piece concepts, but Janggi does not have the horizontal river that divides a Xiangqi board. Janggi also has its own movement and strategic conventions.

Dr. Janggi was developed by SUD Inc.
There is no single tactic that wins every position. Strong play generally depends on board awareness, piece coordination, cannon tactics, long-range control, general safety and careful calculation.
Dr. Janggi brings traditional Korean chess to mobile and Windows devices, combining a distinctive 9×10 board with cannons, chariots, horses, elephants, soldiers and palace-based strategy. The game supports online matches while also being listed with offline functionality.
The biggest step for beginners is learning that Janggi is not simply Korean chess played like Western chess. The cannon's jumping attacks, long-range elephants, open chariot lines and different board structure create their own tactical language.
Start by learning the pieces, then concentrate on cannon screens and long-range threats. Once those ideas become familiar, move toward deeper opening planning, coordinated attacks and endgame calculation. That progression makes Dr. Janggi much easier to understand and considerably more rewarding to play.
