English peg solitaire solution
Start with d4 empty. Make 31 jumps and the last marble lands on d4. This is one verified route, so use it to check your own idea, or to see how an old puzzle is finished.
How to read it
Every jump is written as two holes, like d2 → d4: the marble that moves, then the empty hole it lands on. The marble it jumps over is removed. Every hole shows its name on the board, and the next jump glows. Click any number to see the position after that jump, or use ← / → to step and Space to play.
The route in brief
- Jump 1: d2 → d4. Replay from the start
- By jump 15 the right arm is empty. Show it
- By jump 26 the top arm is empty. Show it
- By jump 29 the bottom arm is empty. Show it
- By jump 31 the left arm is empty. Show it
- Before the last jump only b4 and c4 are left. Then b4 → d4 ends on d4. Show the last jump
Where players go wrong
These jumps look natural, and each one leaves a position that can no longer reach d4.
