What is Stack on Vaults.lol

Stack is one of the free games inside Vaults Games, at vaults.lol/dashboard/games. A block slides back and forth above your tower, and you drop it onto the layer below. Anything that hangs over the edge gets sliced off, so your tower gets narrower every time you miss.

The goal is simple: build the tallest tower you can before the blocks get too thin to land.

Click, tap, or press space to drop the block. That is the only control.

The block speeds up as your tower grows, so the timing window shrinks the higher you climb. Land the block exactly on top of the one below and it counts as a perfect drop, which keeps your tower full width and pays bonus XP.

Perfect drops in a row build a chain. The longer the chain, the more bonus XP each drop is worth, so clean play is worth a lot more than just surviving.

One sloppy drop breaks the chain, so the real skill is staying calm once the speed picks up.

Stack feeds the same XP pool as every other Vaults game. Your XP is verified on the server when the run ends, so it counts toward the same level, rank and badges as Type Rush, Flight, Dash and Archers.

Your best tower is saved to your account and shows on the Progression page.
