Stack. Clear. Blast. Quest. Carve. StarrBlocks is a native iOS puzzle arcade built for quick rounds, deep mastery, and that "one more run" pull. Start with StarrBlocks, a polished falling-block puzzle with smooth swipe-and-tap controls, satisfying rotations, hard-drop trails, rich haptics, and line clears that pop. Switch to StarrBlast, an 8x8 drag-and-place block puzzle with its own modes, themes, daily challenges, and cinematic blast effects. Then there's StarrWood, a tactile 9x9 Woodoku puzzle: drag carved wood pieces onto the board, clear rows, columns, and 3x3 sudoku boxes, and wander a Journey trail of hand-painted polaroid scenes you unlock one level at a time. We've also got StarrTricks, a tower height game mode where you see just how high you can stack the blocks without letting the pieces topple over! FOUR PUZZLE GAMES IN ONE STARRBLOCKS Marathon: classic endurance. Survive rising speed and chase a bigger score. Sprint: clear 40 lines as fast as possible. Ultra: three-minute blitz where every placement matters. Bombs: chain explosive clears and turn pressure into fireworks. STARRBLAST Classic: endless 8x8 block placement with no falling timer. Daily: a shared daily seed with streaks and one clean run per day. Quest: 90 story levels with handcrafted boards, objectives, collectibles, and stars. STARRWOOD Endless: free-play 9x9 Woodoku with sudoku-box clears, scattered collectible gems that bonus your score, and randomized painterly backdrops on every open. Journey: hand-authored 30-stop trails (starting with Camping) where the screen scenery shifts between polaroid scenes — campfire, lakeside, summit, sunrise — as you collect themed gems against a move limit. THEMES WITH PERSONALITY STARRTRICKS Tower: physics-based tetromino stacking where every block has weight, wobble, and consequence. Build upward across checkpoint lines, brace risky pieces with Anchor power, and chase your tallest tower in feet. Play across 30+ custom themes, from Aurora, Cosmic, Jelly, Tron, Atoll, Aquarium, Trench, and Prism to StarrBlast worlds like Ocean Depths, Crystal Gems, Ancient Relics, Gridrunner Protocol, and Phantom. StarrWood adds a hand-painted wood-grain family with multiple stains for every Woodoku run. Themes change more than color: boards, pieces, backgrounds, trails, particles, and line-clear effects all get their own personality. EFFECTS THAT FEEL GOOD Hard-drop trails show the path your piece took. StarrBlast line clears turn rows and columns into radiant blasts. StarrWood Journey backdrops shift painterly scenes as you walk the trail. Custom effects, particles, screen motion, and haptics make every clear tactile. A 21-track soundtrack and sound effects can be mixed, muted, or tuned to your mood. BUILT FOR HOW YOU PLAY Responsive controls designed for thumbs Local high scores and run history Game Center leaderboards for score-based modes Playable onboarding that gets out of your way Music, sound, haptics, ghost pieces, classic pieces, and visual options Native SwiftUI polish with smooth animation on iPhone and iPad NO NOISE No ads. No timers between rounds. No paywalls blocking the good stuff. Just open the app, pick your mode, and chase the next clear. StarrBlocks is for players who love thoughtful puzzle design, satisfying feedback, and games that turn a spare minute into a real run.
