Trace IQ is a brain-teasing number puzzle game by Sudeveloper. Draw one route from A to B through every tile on the board, and make its value land exactly on the target. Simple to learn, surprisingly deep to master.
How to play
- Start on A and drag your route all the way to B.
- Pass through every tile on the board — none can be skipped.
- Move up, down, left or right. No diagonals.
- Your value starts at 0, and each tile changes it: +5 adds, −3 takes away, ×2 doubles and ×0 wipes it back to zero.
- Order matters: +5 then ×2 makes 10, but ×2 then +5 is only 5.
- Reach B with your value exactly equal to the TARGET.
Features
- 500 levels, from gentle warm-ups to brain-bending 5×4 boards.
- Multiple targets per level — solve one target and the next one flows in through the pipe, on the very same board.
- Hints and skips when you are stuck, unlocked by watching a short ad.
- Beautiful themes, including Snow and Midnight.
- Satisfying piano sounds, particle effects and a party celebration for every solved level.
- Free to play.
