About

Bottom Up!

Features
Read full description

Every tower has a weak spot. Find it. Bottom Up! is a physics puzzle about taking a tower apart and building it higher at the same time. Pull a block out of the stack, drop it on top, and repeat until something up there touches the goal line. Simple enough. Now do it without bringing the whole thing down. HOW IT PLAYS • Press and hold any block to lift it out of the tower. • The rest of the stack reacts instantly. Real physics, no scripted collapses. • Carry it up and let go. A dashed guide shows you exactly where it will land. • Get any piece to reach the goal line and the level is yours. WHAT MAKES IT HARD • Steel blocks are riveted in place. They never come out, so plan around them. • Glass shatters under a heavy drop. Small pieces land safely. Big ones do not. • Blocks come in shapes: plugs, rods, long beams, L-corners, zigzags. Every shape sits differently, and an overhang that looks fine may not be. • Pull the wrong piece and the tower rarely falls at once. It leans. Then it decides. 28 HAND-BUILT LEVELS Every level is a designed puzzle, not a random pile, and every single one has been proven solvable by a solver running the exact same physics you play on. If you are stuck, there is a way through. The campaign opens wide and forgiving with simple rods, then brings in corners, steel, glass, zigzags and towers riddled with holes. By the end you will be reading a stack the way a builder does. STUCK? TAP THE HINT Hints are free and unlimited. Tap the button and the safest block to pull right now lights up for you. No currency to spend, no waiting, no limit. ANYWHERE, ANYTIME • Plays in portrait with one hand. • No connection needed to play. • Levels are quick, but the tower is never in a hurry. • Sound and vibration, each switchable off. There is no timer and no move limit. Take as long as you like, study the stack, and pull the one piece the tower can live without. Pull it out. Stack it up. Reach the top.
