Medium American checkers
Medium American checkers is the default opponent on Checkerso. Same board and rules as American checkers: forced jumps, no flying kings, promotion ends the turn.
Easy looks one move ahead and Hard looks five. None of the three difficulties change the rules.
American checkers at Medium strength
Leave the other side with no pieces, or no legal move. Men move diagonally forward; kings move one square diagonally. If you can jump, you must.
- Men do not move or jump backward.
- Promotion to king ends the turn — no continuing as a king that same jump.
- You may choose any legal jump line; longest capture is not required.
What the Medium opponent calculates
The Medium opponent looks three moves ahead, counting each side's turn: its move, your reply, and its next move. When a jump is on the board it keeps looking until the captures are over.
It prefers positions where it has more pieces and more moves available.
It catches straightforward threats but not every long combination.
Steady play at Medium
Trade when you are ahead
If you lead by a man or a king, simplifying the position is often correct. Medium will still fight, but fewer pieces mean fewer places for you to slip.
Time your promotion
Crowning stops your turn. Promote when the new king is safe or when promotion wins material on the previous jump — not when it walks into an immediate capture.
Avoid the side rail
A man on the edge has half the escape routes. Slide toward the center before you commit to a long jump line Medium can read.
American checkers difficulty levels compared
| Level | Best for | How far it looks | Typical gap | Practice focus |
|---|---|---|---|---|
| Easy | Learning forced jumps and king promotion | 1 move ahead (its own; never your reply) | Never checks your reply, so it often leaves a man you can jump | Open from the center and set up simple two-for-one jumps |
| Medium (this page) | Regular play and steady improvement | 3 moves ahead; follows jump sequences to the end | Spots obvious one-move blunders; shorter endgame plans | Trade when ahead; keep the back rank intact longer |
| Hard | Players who want more calculation | 5 moves ahead; follows jump sequences to the end | Stops at five moves ahead, so it is not master strength | Work through forced jump lines before you touch a piece |
