What are the rules of international draughts?

Pieces move one square diagonally forward. They capture by jumping an opponent's piece, forwards or backwards, and must keep jumping while they can. Capturing is compulsory, and you must take the route that captures the most pieces. A piece that ends its move on the far row becomes a king, which moves and captures any distance along a diagonal.

How is it different from checkers?

International draughts uses a 10×10 board with 20 pieces each instead of 8×8 with 12. Ordinary pieces capture backwards too, kings fly, and the majority-capture rule applies: you must take the most pieces you can.

When does a piece become a king?

Only if it ENDS its move on the far row. A piece that passes over the far row in the middle of a capture and jumps back out stays an ordinary piece.

How to play

1. Move

Tap one of your pieces, then a green dot. Pieces move one square diagonally forward.

2. Capture

Jump over an opponent's piece to take it. If you can capture, you must, and keep jumping while you can.

3. Crown a king

Reach the far row to become a king, which moves backwards too. On Flying kings and International, kings slide far.

4. Climb the levels

Beat a level without undo or hints to open the next, from Beginner up to Master.

About international draughts

International draughts is played on a 10×10 board with 20 pieces each, on the dark squares of the first four rows. It is the draughts of the world championship and the African championship, and the game most people mean by “dames” in French-speaking countries.

It differs from 8×8 checkers in three ways that make it deeper: ordinary pieces capture backwards as well as forwards, kings fly along a whole diagonal, and when several captures are possible you must take the route that captures the most pieces.

On Ganzaa you play it against the computer at six levels. Beginner plays any move, so you can learn the rules; Master thinks for two seconds a move. Undo and hints are there while you learn, and a level opens only after a win without them.

How to play checkers: the rules

Checkers, also called draughts, is played by two players on the dark squares of a chequered board. You move diagonally, capture by jumping over your opponent's pieces, and win when your opponent has no piece left or cannot move. Ganzaa has three rule sets; here is each one in full.

The board is 10×10. Each player starts with 20 pieces on the dark squares of their first 4 rows.
Pieces move one square diagonally forward, onto an empty dark square.
Capture by jumping over an opponent's piece to the empty square just beyond it. Ordinary pieces may capture forwards AND backwards.
If you can capture, you must. After a capture, keep jumping with the same piece while you can.
When there is a choice, you must take the route that captures the most pieces.
A piece that ENDS its move on the far row becomes a king. Passing through it during a capture is not enough.
Kings are flying kings: they move and capture any distance along a diagonal, forwards and backwards, and may stop on any empty square beyond the piece they take.
You win when your opponent has no piece left or can't move. The same position three times, or 25 moves each with no capture and no ordinary piece moved, is a draw.

Tips to win at checkers

1. Hold the centre

Pieces in the middle of the board reach both sides and are hard to trap; pieces on the edge have half the moves.

2. Keep your back row

Pieces left on your first row stop your opponent crowning. Move them last.

3. Move together

A piece on its own is easy to capture. Advance pieces side by side so each one guards the next.

4. Look for the forced capture

Capturing is compulsory, for both players. Offer one piece and your opponent must take it, which can open a double or triple jump for you.

5. Trade when you are ahead

With more pieces, swap one for one: every exchange makes your lead count for more.

6. Crown a king, then use it

A king moves backwards too, and in International and Flying kings it crosses the whole board in one move.
