Number Trail

Combine number tiles with operations to reach a target. The calculation trail explains every move.

5–15 min 1 learner

How it works

1. Use each tile at most once; unused tiles are allowed. Choose two tiles and an operation. Undo and try another route.
2. Read the explanation after each mission. Hints are always available.
3. Choose any mission or resume a local checkpoint. Progress is practice history, not a certified grade.

Controls: Keyboard / tap / labeled controls
