Diamond peg solitaire solution
Start with d2 empty. Make 39 jumps and the last marble lands on f2. 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 f2 → d2: 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: f2 → d2. Replay from the start
- By jump 30 the bottom tip is empty. Show it
- By jump 33 the right tip is empty. Show it
- By jump 36 the left tip is empty. Show it
- Before the last jump only d2 and e2 are left. Then d2 → f2 ends on f2. Show the last jump
Where players go wrong
These jumps look natural, and each one leaves a position that can no longer reach f2.
