Choose a route to the answer
If the target is 10, start with 3, add 2, then add 5. A correct calculation clears the tiles you used. Look for other routes to the same target using the numbers currently on the board.
Calculate in selection order
Each new tile acts on your current value. Choose 3 → +2 → ×4: first make 5, then multiply by 4 to reach 20. This differs from conventional operator precedence, so follow the current value shown in the game.
A short calculation or a longer one?
A short calculation can clear tiles quickly. A longer one can clear more at once. New tiles keep arriving while you decide, so weigh the time spent against the space you can clear. The run ends at 100% occupancy.
