The first level of every pack is always open, so you can jump to level 211 (10×10) right now; inside a pack the next level unlocks when you solve the previous one.
What makes a level harder
- Board size. More cells means more routes and more empty pockets to account for. A 14×14 board has 196 cells against 16 on a 4×4.
- Fewer colors for the size. Inside each pack the number of colors drops from the top of the range to the bottom as the levels go on. Fewer colors means longer lines that snake across the board, and long lines are where the detours hide.
- No short cuts in the solution. The generator rejects layouts where a dot touches its own line or a color fills a 2×2 block, so every line has a reason to go where it goes.
Suggested path
Finish 4×4 and 5×5 to learn the “fill every cell” rule; most players earn three stars there within a few tries. Boards from 6×6 to 9×9 teach edges, corners and counting; read the tips if you get stuck. From 10×10 on, solve region by region. After level 660 the endless 15×15 mode keeps generating fresh boards forever.
Stars per level
Each level stores your best result: ★★★ for a perfect solve (one move per color, no hints), ★★ for a clean solve with extra moves, ★ when a hint was used. The level grid shows the stars under each number, and the home screen adds them up.
FAQ
How many levels are there?
660 levels in 11 packs, from 4×4 to 14×14, and then an endless 15×15 mode with no last level.
Are the levels the same for everyone?
Yes. Levels are generated from a fixed seed, so a level number always gives the same board. The daily puzzle is also shared by all players.
Can I skip a level?
Within a pack you need to solve the previous level, but the first level of every pack is open, and hints are unlimited, so no level can block you permanently.
