BlockDrop is a beautifully simple block puzzle game. Drag shapes from the tray onto the 8×8 board, fill rows or columns to clear them, and try to beat your high score. WHY YOU'LL LOVE IT • No ads. Ever. No banners, no pop-ups, no video interruptions. • No paywalls. The whole game is free to play — the only purchase is an optional tip if you'd like to support development. • Play offline. No account, no sign-up, no internet required. • Pick up where you left off. Take a call or close the app mid-game and your board, score, and even your undo history are saved. WHAT MAKES IT DIFFERENT • Diagonal clears. Fill a full corner-to-corner diagonal to clear it — a twist most block games don't have. • A new Daily Puzzle. The same board for everyone, every day — climb the daily leaderboard. • The Beetle Hunt. A hidden beetle scurries across the daily board — box it in to earn bonus swaps and a confetti payoff. • Wildcard pieces. Stuck? Earn a "?" piece and turn it into any shape you want. • Challenge a friend. Share a seed code and your friend plays your exact piece sequence — then compare scores. • Undo. Made a mistake? Take it back — most block puzzles won't let you. • Rotate pieces. Spin blocks to slot them into tight spots. • Free shuffles. Earn shuffles as you score to swap out an awkward tray. MAKE IT YOURS • Customize the grid cell colors and opacity to match your style. • Sound and haptics you control. COMPETE • Game Center leaderboards for regular play, the daily puzzle, and efficiency (points per move). • Daily "king of the hill" rewards for holding the top spot.
