Daily Tango & Star Battle

How to play

Three logic puzzles a day, about five minutes: a Tango warm-up, an 8×8 Star Battle and a 9×9 Star Battle. Each one has a single solution and never needs guessing.

Tango: fill every cell with a sun or a moon (tap once for ☀, twice for ☾). Every row and column is half suns, half moons; never three alike in a row; cells joined by = match, by × differ. Tango rules and tips.

Star Battle: place one ★ in every row, every column and every colour region; stars never touch, not even diagonally. Tap once for a dot (no star here), again for a star, drag to dot many cells. Star Battle rules and tips.

Learn single candidates, cell elimination and confinement.
