Full description

Sumknot is a crossword built out of equations. The figure is irregular on purpose. Equations cross at shared cells, so a single number closes two of them at once - and has to be right twice. Slide the tiles into the frame until every line reads true. One rule to know before you start: arithmetic here runs strictly left to right, with no operator precedence. 2 + 3 x 4 is 20, not 14. It is not a simplification of school arithmetic, it is a smaller rule, and it makes every line readable in one pass. Every figure is generated and then proved by our own solver: exactly one solution, reachable by logic alone. • DAILY - the same figure for everyone, once a day. Beat the clock, keep your streak, share your result without spoiling it. • LEVELS - 150 figures in three chapters, from four-tile openers to knots that cross a dozen times. • ENDLESS - a fresh figure whenever you want one, with a code you can send. Made to respect your time: • No lives, no forced timers, no forced videos. • Gold, silver or bronze on every board, by how close you came to par. • Three hints on every board. • Colour-blind shapes, high contrast and a choice of palettes. • Dark mode. Works offline. Tiny download. • No sign-up and no accounts: progress stays on your device. A quiet knot of numbers for a coffee break.
