Logic puzzles leave nothing to chance: every one has a solution you can reach by reasoning. GameBox.az has 10 of them, all played solo and all comfortable on a phone.
Sudoku is the classic 9×9 number puzzle. In Binairo you fill the grid with black and white circles, in Tents you place one tent next to every tree, and in Light Up you position bulbs so that every square is lit. Minesweeper has you deducing mines from the numbers you uncover, Memory Match tests your recall of pairs, and in Ripple you try to still the whole pond.
Most of them let you choose the difficulty. All except Minesweeper have a daily puzzle that is the same for everyone.
