Frost Vault is a fast, one-thumb arcade climb set in a frozen shaft. A snow orb rises on its own up a narrow channel strung between two seams, climbing higher every second, and your one job is to keep it on the safe side with a single tap.

The controls are a single touch. Tap anywhere and the snow orb arcs instantly across to the other seam; tap again and it swings back. Only one seam is ever blocked at a time — a icicle builds ahead on one side, so read the channel, choose the clear seam, and be there before it arrives. Share a seam with a icicle as you pass and the snow orb takes a hit.

Glowing crystals drift along the open seam between the icicles. Ride that side as you sweep past one and it is banked for bonus points, so the safest route and the greediest route are rarely the same. A hit costs one frost charge, not the whole run — you carry five near the bottom and three higher up — so a mistimed jump is a lesson, not the end. Reach the target height and the front breaks, carrying you up to the next shelf.

Ten shelves climb from a gentle 450-metre opener to a dense, fast 1750-metre finish, each a little quicker and tighter than the last while your margin for error narrows. Nothing here is decided by luck or a wallet: there is no forced ad between runs, no energy timer, and nothing to buy. Every shelf can be cleared with better timing alone, and your progress is saved on the device as you climb, one front at a time.
