Jelly Links
NewA jelly-bright sudoku twist: fill every row, column and connected line with unique numbers across 1,000 puzzles. No timer, no lives — free to play in your browser at PlayKovo, no download or sign-up.
Play Jelly Links Online for Free
Jelly Links takes the logic of Sudoku and adds a twist: lines of connected beads act as their own group, just like a row or column, so every number still has to appear exactly once. Start with gentle 4x4 warm-ups and work your way up to 12x12 boards that demand real focus. With 1,000 numbered stages plus a 500-level Sandbox mode with a single clue per board, there's no timer pressure and no lives to lose — just pure logic at your own pace. A short tutorial teaches the line rule before you dive in, and a hint button is there if you get stuck.
How to play
Fill every row, column and connected line with the numbers 1 to N, using each number exactly once. Beads with a gold ring are yours to change; the rest are fixed clues. Lines of connected beads count as their own group. Use Hint if you're stuck, or Reset to clear your entries and start the board over.
Controls
Tap a bead to change its number, tap again to cycle through values. Pinch with two fingers (or scroll the mouse wheel) to zoom in on larger boards.
