Fit the pieces. Clear the lines. Keep the board alive. FlowBlocks is a block puzzle with one simple loop and a lot of room to think. Drag blocks onto a 9x9 grid. Fill a whole row or column and it clears. Clear more than one at once and a combo builds, and the longer you keep it running the faster your score climbs. There is no timer and nothing chasing you. The only pressure is the board itself: every piece you place decides which pieces still fit afterwards. WHAT IS IN IT - Levels with score targets to work through, and a personal best to beat - A combo system that rewards planning a few moves ahead - Themes to unlock and seven music tracks - One-handed play in portrait, on phone and tablet - English, German, Spanish, French, Japanese, Korean, Portuguese and Russian NO ACCOUNT, NO CONNECTION Nothing to sign up for and nothing to log into. The game runs fully offline, so it plays the same on a plane or underground as it does at home, and your progress stays on your device. ABOUT ADS FlowBlocks is free and supported by ads. If you would rather play without them, one purchase removes them for good. No subscription. For anyone who likes block puzzles, logic games, and something quiet to pick up for two minutes or forty.

You know the moment. Three pieces drop into the tray, none of them fit anywhere, and you realise the run ended two moves ago — not because you played badly, but because the game handed you a hand that was never playable. Gridlock doesn't do that. Every tray is checked before it reaches you. You will still lose, often. But you'll lose because you filled the board and ran out of room, which is your own doing and fixable next time. HOW IT PLAYS Drag three pieces onto an 8x8 grid. Fill a row or a column and it clears. Clear on back-to-back moves and the combo multiplier climbs. Pieces don't rotate, and the tray only refills once all three are gone. So each round is a small planning problem rather than a reflex test — which is why it works equally well in a two-minute gap or a long evening. That's the whole game. Nothing to unlock, no meters refilling in the background, nothing asking you to come back at six o'clock. TWO WAYS TO PLAY Endless — one board, one score, until nothing fits. Daily Challenge — the same board as every other player, every day. ABOUT THE ADS Gridlock is free and supported by advertising, so here is exactly what that means: never an ad before your first game, and never more than one between games. If you want three fresh pieces after a run ends, or more undos, you can choose to watch one. Nothing else. ALSO Undo your last moves, because everyone misclicks. Works offline. No account, no sign-in. Your scores stay on your phone.
