Knight Sums

Addition · 30 levels

Leap the knight so every row hits its total.

How to play

1. The knight hops in an L: two squares one way, one square sideways. Tap a glowing square to leap.
2. Each square it lands on adds its number to that row's plate (later the column's too). The start square counts.
3. Make every plate show exactly its target. No square twice; a 0 plate means keep out.

Start with the plates that are 0 or small: they tell you which squares the knight must avoid. Black pawns block squares.
