About this game
One empty square, fifteen tiles, one order. Slide until every number sits at home. Board 4×4.
Scoring & tips
- Work one corner at a time; a fixed order beats random movement.
- Say the position out loud when you see it — it doubles the recall.
- Slow down. Almost every loss here is a move made before thinking.
