Build a taller tower without popup ads breaking your focus. Drop each block at the right moment, save shaky stacks, and chase a perfect streak you can check at a glance on your widgets. Block Tower: Stack Builder helps casual players build towers with one-tap drops and keep track of personal bests. PERFECT WHEN • You are waiting for coffee and want one quick Classic mode run with a clean one-tap drop. • Your Home Screen widget shows the current seasonal theme and you want to open a fresh run right away. • Your tower is leaning after a rough landing and you need a Perfect streak to win back lost width. • You want a stack game that feels like a fidget toy, with Haptics and Sound Effects you can switch on or off. • You want to share a game-over result with Share Run after a strong tower game session. HOW IT HELPS Drop blocks with one tap as each piece swings over the tower, then watch the stack settle. Clean landings count as Perfect or Near-Perfect, rough drops can trim the overhang, and a Wobble-Save can rescue a tower that almost falls. Hit three Perfect drops in a row and the next block can recover some lost width. You start with three lives, and your run ends when the tower finally topples. Keep your tower game moving with controls that stay out of the way. The pause button lets you resume, restart, or switch between Classic, Wind, and Earthquake modes. Wind adds a steady sideways push that makes each drop trickier, while Earthquake shakes the ground and tests how well your stack holds together. Your tallest tower, longest Perfect streak, and total runs are saved as Your Best and shown again when you come back. Make the game feel like your own with skins and themes. Pick from free block skins like Wood, Stone, and Brick, then change the look of the whole scene with themes such as Midnight, Spring, Summer, Autumn, Winter, Aurora, and Festival. The active theme also appears on your share card and widgets. Add a Home Screen, Lock Screen, or StandBy widget to see your best height, best streak, total runs, and the current season without opening the app. WHY IT WORKS This stacker is built for short, focused play: tap, drop, recover, and try again. There are no mid-run ad breaks, and your next game is always close with a widget, a Shortcut, Spotlight, or a Control Center control that starts a fresh tower run. PAID FEATURES Pro adds unlimited lives, extra challenge modes with Wind and Earthquake, more themes, and more skins including Gold, Crystal, Neon, Obsidian, Marble, and Cosmic. Cosmetic skins do not change the physics. If you share a result or use widgets, the app needs the usual system access for those features. Stack a few blocks, chase a new personal best, and see how high you can build today. Terms of Use (EULA) - http://www.apple.com/legal/itunes/appstore/dev/stdeula
