Monoblast
Read full descriptionHide full description
Monoblast is a block puzzle stripped to its purest form: a strict black-and-white board where the only color in the whole game is the blocks themselves — seven shots of saturated neon. No timers. No clutter. No rainbow noise. Just you, an 8×8 grid, and the quiet satisfaction of a clean line clear. HOW IT PLAYS • Drag blocks from your tray onto the board, wherever they fit. • Fill any full row or column and it clears instantly. • Clear lines on back-to-back moves to build a combo and multiply your score. • It's game over when none of your three pieces fit — so plan ahead. A PUZZLE A DAY Take on the Daily Challenge — one puzzle that's identical for every player, every day. Finish it to grow your streak, and don't let the chain break. MADE YOURS Unlock cosmetic skins that re-color the neon — Neon, Pastel, Terminal and a color-blind-safe palette — without ever touching the clean black-and-white shell. PLAYS ANYWHERE • Fully offline. • One-handed drag-and-drop controls. • A color-blind-safe mode with a distinct shape inside every block. • No account required. Free to play. Remove ads any time with a single optional purchase. Skins are cosmetic only — never pay-to-win. Drop a block. Clear a line. Keep the streak alive.
