How to play
Play Sum Sprint free online
Sum Sprint turns a chalkboard of digit tiles into a free online number puzzle about adding fast. Tap tiles whose digits add up exactly to the MAKE number on the slate, and the chain clears while the tiles above fall down. Go over and the chain resets. Long chains leave bombs and equal digits leave jokers. It plays in the browser on phone or computer, no sign-in. A clock mode adds a draining bar to each target for extra pressure.
How to play Sum Sprint
- Tap number tiles that add up to the MAKE number.
- Four or more tiles leave a bomb (3x3 blast); equal digits leave a joker that pairs with any one tile.
- Clock mode: clear fast for +3 seconds before the bar drains. Stack mode: do not let a column fill.
Sum Sprint tips
- Plan a chain before tapping, since going over the target resets it and wastes seconds.
- Clear four or more tiles to leave a bomb, then tap it to blast the block around it.
- Chain two equal digits to leave a joker, which pairs with any single tile to hit the target.
Sum Sprint questions
- Can every round be solved?
- Yes. The target is always built from tiles on the board.
- What is Stack mode?
- No clock. Tiles keep dropping and a full column ends the run.
