About CancelWise
CancelWise is a daily number and logic puzzle played on a grid of positive and negative numbers, with a target sum shown at the end of each row and each column. The aim is to cancel some cells so that the numbers left in every row and column add up to their targets.
Each date carries four grids in rising difficulty: easy, medium, hard and expert. You click a cell to cancel it, which drops its value from the sums of its row and its column. When a line's remaining numbers match its target the sum turns green, and the puzzle is solved once every row and column is green. A timer tracks how long you take, and the game keeps your times, a streak and a result you can share.
The grids are generated from the date, so everyone playing on a given day gets the same puzzle, and arrows at the top step back through the last seven days. The grids grow with difficulty, from 3x3 on easy to 6x6 on expert, so easy is a quick warm-up while expert is a longer sitting.
It suits players who like short arithmetic logic puzzles and want to choose how hard their session is. It runs in the browser, is free, shows no ads and needs no account; the maker takes questions and feedback on Bluesky.

Tips
- Start from a row or column whose current total is far from its target: it tells you roughly how much you still need to cancel.
- A cancelled cell leaves both its row and its column, so look for cells that help two lines at once.
- Watch the negative numbers: cancelling a negative raises that line's total, so decide whether you need to remove it or keep it.
- Try easy first to see how the targets respond, then move up; the higher levels use bigger grids.
