Lights Out is the fifth game on IOTL Games — the classic 1995 Tiger Electronics handheld puzzle, reimplemented as a daily browser game. Tap any cell: it and its four orthogonal neighbours (up, down, left, right) toggle on or off. The goal is simple — turn every light off. Four difficulty levels — Easy (4×4 grid), Medium (5×5, the classic Tiger size), Hard (6×6), Extreme (7×7). Every board is solvable by construction (starts from all-off, then random taps — same taps in any order turn it back off). Same daily board per level (seeded by UTC day × level). Best moves + best time saved per level per board in your browser.
