International Draughts — The 10×10 Version of Checkers
Learn the rules and differences of International Draughts, the global competitive version played on a 10×10 board.
What Is International Draughts?
International Draughts (also called 10×10 draughts) is the version of checkers played on a 10×10 board with 20 pieces per side. It’s the most widely played competitive form of checkers globally, with organized championships in Europe, Africa, and Asia.
While standard American/British checkers uses an 8×8 board with 12 pieces each, International Draughts adds a larger board, more pieces, flying kings, and the maximum capture rule — all of which make the game significantly more complex.
Key Differences from Standard Checkers
| Feature | Standard Checkers (8×8) | International Draughts (10×10) |
|---|---|---|
| Board size | 8×8 (32 playable squares) | 10×10 (50 playable squares) |
| Pieces per player | 12 | 20 |
| King movement | One square diagonal | Any distance diagonal (flying king) |
| Capture rule | Choose any available jump | Must choose maximum capture |
| Men capture backward? | No (standard) | Yes |
| King promotion | Turn ends after crowning | Can continue jumping |
Rules Specific to International Draughts
The Flying King
The biggest gameplay difference. When a piece is crowned in International Draughts, it becomes a flying king — it can move any number of squares along a diagonal line, like a bishop in chess.
This makes kings much more powerful than in standard checkers. A flying king controls entire diagonals and can attack from distance.
Maximum Capture Rule
When multiple capture sequences are possible, you must choose the one that captures the most pieces. This adds a layer of calculation to every tactical situation — you need to count the captures in each possible sequence.
Men Can Capture Backward
In International Draughts, regular pieces (men) can capture backward as well as forward. They still can only move forward, but their jump capability extends to all four diagonal directions.
Promotion and Continuation
If a piece passes through the king row during a multi-jump sequence, it does not get promoted mid-sequence. It must end its turn on the king row to be promoted. However, a king that is already crowned can continue jumping on the turn it is created if another jump is available.
Strategic Implications
Kings Are Game-Changers
Because flying kings are so powerful, a single king on the board can dominate. King promotion carries even more weight than in standard checkers.
Deeper Calculation Required
The maximum capture rule means every move requires counting and comparing capture sequences. This makes the game more demanding tactically.
Wider Board Means More Options
With 50 playable squares instead of 32, and 40 total pieces instead of 24, there are more possibilities on every move. Games tend to be longer and more complex.
Backward Captures Change Dynamics
Since men can jump backward, pieces are never truly “safe” behind the front line. This changes formation strategy and makes defense more active.
Competitive Scene
International Draughts has:
- World Draughts Federation (FMJD) — the governing body for international competition
- World Championship — held regularly since 1948
- Strong computer programs — used for analysis at the highest levels
- Popularity in: Russia, Netherlands, France, West Africa (especially Senegal), and many other countries
Getting Started
If you’re coming from standard 8×8 checkers:
- Learn the rule differences — flying kings and maximum capture are the big changes
- Play slowly at first — the larger board takes time to scan
- Practice counting captures — the maximum capture rule requires careful calculation
- Study king endgames — flying kings create completely different endgame dynamics
