A jelly-bright take on Sudoku. Every row, every column and every connected line must hold each number exactly once. 1000 puzzles from gentle 4x4 warm-ups to 12x12 boards that really make you think, plus a 500-stage Sandbox. No timer, no lives — just you and the logic.
Fill every row, every column and every connected line with the numbers 1 to N, using each number exactly once.
- Tap a bead to change its number. Tap again to cycle.
- Beads with a gold ring are yours to change. The rest are fixed clues.
- Lines are the twist — beads joined by a line form a group of their own, just like a row or a column.
- Pinch with two fingers to zoom in on the bigger boards. (On desktop: mouse wheel over an empty area.)
- Stuck? HINT fills in one bead for you. RESET clears everything you entered and leaves the clues.
Three ways to play
- Tutorial — 3 short boards that teach the line rule.
- Normal — 1000 stages. Boards grow from 4x4 to 12x12 and clues thin out as you go.
- Sandbox — 500 open boards with a single clue. No guidance, just the line structure.
