About

Shift The Disks

Features
Read full description

Shift the Disks is a beautifully simple yet brain-teasing puzzle game inspired by the classic Towers of Hanoi. Your goal is to move all the disks from the leftmost tower to another, one move at a time, following a few clever rules. * Move only one disk at a time. Only the top disk of any tower can be moved. Larger disks can't go on top of smaller ones. * Tap a tower to select its top disk. Tap another tower to place the selected disk. Win the game by stacking all the disks on a different tower. Shift the Disks is fully compatible with VoiceOver and designed from the ground up to be accessible for blind and low-vision players. Every move, tower, and disk is clearly announced, making the experience intuitive and enjoyable for everyone. Whether you're a puzzle veteran or just looking for a relaxing brain workout, Shift the Disks delivers a timeless challenge you'll want to solve again and again. We would like to thank Ahmad Albahar for his help in testing the game.

Erwin is a sliding puzzle played on the six faces of a cube, a unique 3D experience with spatial audio and holographic depth effects. Swipe to slide and merge tiles, or swipe the background to rotate the cube and work the other sides. Tiles have a value that doubles when they merge, and each merge adds to your score. Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values, some entangled and move together, and some even teleport. Play together with friends via Game Center Multiplayer: take turns on a shared cube, watch each other's moves in real time, and climb the cooperative leaderboard. Universal purchase with Family sharing: pay once, and play Erwin on iPhone, iPad, and Mac, with up to six family members. Erwin respects your privacy and your wallet. This is an app I wanted for myself without compromise or dark patterns: pay once and it's yours, on all your devices, with no ads, no nagging in-app purchases, no tracking, no profiling.
