About

Quad Drop

Features
Read full description

Quad Drop is a falling-blocks puzzle game. Pieces drop from the top of the grid โ€” rotate them, slide them into place, and pack each row tight. Fill a complete row to clear it and score. The game ends if the stack reaches the top, so keep your lines clearing and the board low. Itโ€™s a clean, fast take on the classic block-stacking puzzle: easy to pick up, hard to put down. The whole game is free, with no ads and no in-app purchases. How to play Swipe to move pieces, tap to rotate, and long-press to hard-drop a piece straight to the bottom. Soft-drop on the way down for a few extra points. Plan your moves Hold piece: stash a piece and bring it back at the perfect moment Next-piece preview: see whatโ€™s coming and plan ahead Ghost piece: a preview shows exactly where the current piece will land 16 speed levels Start at a relaxed one piece per second. Every 10 lines you clear bumps you up a level and the pieces fall faster โ€” all the way to a white-knuckle final level. How far can you go? Score big Clear one, two, or three rows at a time, or clear four rows at once for the biggest payoff. Your high score is saved, so you can chase your personal best every run. Themes and color schemes Play in light or dark mode, and pick the block colors that work best for you: Noir Neon โ€” bold, high-energy colors on a black grid Classic โ€” the traditional bright block colors High Contrast โ€” a colorblind-friendly palette designed for maximum distinguishability Deuteranopia โ€” tuned for red-green color vision Your theme and color scheme are saved automatically. Play anywhere, offline Quad Drop works completely offline โ€” no connection needed, on the couch or on a plane. Your game and high score are saved on your device, so you can stop anytime and pick up exactly where you left off. No ads, no purchases, no accounts The full game is free. No ads, no in-app purchases, no sign-ups, and no data collection. Quad Drop runs entirely on your device. Whether youโ€™ve got thirty seconds in line or a long evening to burn, Quad Drop is ready when you are.
