Tawcorkscrew

Turn the tower and guide a glass marble through the gaps in Tawcorkscrew. Drag to rotate the rings, collect floating prisms, and keep clear of violet plates that crack your marble. Brass rings follow their own rule: every bounce turns them one segment, wherever the marble is. Read their markings and use the ring above to line up a safe drop below. Explore 21 levels across four chapters and earn three separate medals on each: reach the cup, collect every prism in one run, and finish within the bounce par. Replay levels to complete all 63 medals, review your best results, and track how safely you land on brass. Use prisms earned through play to unlock eight cosmetic marbles, with a live 3D preview to help you choose. A three-step introduction and the Tower manual explain the rules. Your progress stays on your iPhone, with no accounts, notifications, or purchases for real money.
