lightON

A captivating, one-of-a-kind puzzle with a stylish retro look and feel.
lightON (enlighten the enigma) is an intriguing, free-to-play logic puzzle that challenges your brain to uncover mysterious patterns! This addictive mind game features unique mechanics initially inspired by the Rubik's Cube. The board consists of a grid of symbol blocks that you can slide by row and column.
Your goal is to reveal the hidden secret pattern by lighting up every block on the sliding puzzle grid. A block is lit when its symbol is in the correct position. If a block is off, you must replace its symbol by shifting and solving the logic grid. You can swipe to move blocks in rows or columns—a mechanic that creates tricky challenges. Remember, tiles wrap around the grid edges. Each wrap-around costs 1 credit, so plan your moves carefully to solve the enigmatic schemes efficiently. To keep the experience frustration-free, there is no time limit for moves.
lightON offers 200 challenging levels with different secret patterns, designed to sharpen your mind and boost concentration! You'll start with small 3x3 grids and just two symbol types. As you advance, levels grow progressively more difficult, testing your mental limits. Climb the ranks, unlock achievements, and unleash your full potential as a sharp-minded puzzle master.
lightON sports an attractive, minimalist retro design that's optimized for all screen resolutions. Its look takes inspiration from vintage calculators and the epic aesthetic of Stanley Kubrick's *2001: A Space Odyssey*, making the game visually distinctive and appealing.
This brain-teasing puzzle shares some traits with unblock, unroll, and sliding games, but with far more possible moves, it can feel both simpler and more complex! Solving lightON aligns with the strategic thinking used in board puzzles like Sudoku, Kakuro, KenKen, and Hitori. Unlike match-3 or connect-the-dots games, lightON relies on pure logic—not randomness or luck. That’s why our motto is:
Prove yourself!

Play lightON.
