SMALL NUMBERS. QUICK SUMS.

Make the target.

Press on a digit and drag through others to add them up. The moment your digits make the target, the sum seals and a new board is dealt. Every board has an answer in a straight line.

Drag back over the previous digit to take the last one off. If you let go on the wrong total, the selection clears and your streak resets.

One clock per round
A round starts with 24 seconds on a 3 × 3 board or 36 seconds on a 4 × 4 board. Solving deals the next board but doesn’t add time, so find as many sums as you can before it runs out.
Score and streak
Every sum is worth a point, and your score carries into the next round. The streak counts sums in a row without a wrong total.
