# Knight Sums

Addition · 30 levels

Leap the knight so every row hits its total.

## How to play

- The knight hops in an L: two squares one way, one square sideways. Tap a glowing square to leap.
- Each square it lands on adds its number to that row's plate (later the column's too). The start square counts.
- 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.
