Sumtrail

How to play Sumtrail

1. Your trail starts in the green top-left cell and must finish in the gold bottom-right cell.
2. Move one cell up, down, left or right at a time. You cannot visit a cell twice.
3. The digits on your trail must add up exactly to the target. Any route that does this wins.
4. Your time is your score. Tap a cell already on your trail to step back to it.

Tips

Work out roughly how many cells you need: divide the target by 5 (the average digit). Hug the edges when you need a long, low-sum trail, and cut through the middle when you need big digits fast.
