About this game

A secret combination. A few tries. No second chance.

Battle Vault is a deduction game: find the combination of pawns that opens the vault. After each attempt, you learn how many pawns are in the right place and how many are present but misplaced — never which ones. It's up to you to cross-check.

FOUR WAYS TO CRACK A VAULT

DEDUCTION — The clues pile up, logic does the rest.
MEMORY — The combination appears, then vanishes. Remember it.
FRAGMENTED MEMORY — Pawns flash by in groups, out of order.
MIXED — Keep what you saw, deduce what was hidden.

THE CAMPAIGN: 150 VAULTS

Five chapters, 150 levels, and a difficulty that climbs without warning. The first vaults give in easily. Further on, protocols join in: corrupted palettes, scrambled history, sealed locks, a ticking clock. Every level sets its own mode — no sticking to what you already know.

TWO PLAYERS, NO INTERNET

One phone each, nothing else. The devices talk directly over the local network or a simple hotspot: no server, no sign-up. A code is all it takes to join the game.

You can also play two players on a single device, passing it back and forth.

CO-OP AGAINST THE AI

Ten levels where the vault fights back. The opponent doesn't wait for your turn and doesn't forgive guesswork — the final showdown has to be earned. Playable as a pair, or solo in Infiltration.

AND MORE

Challenges to complete, rewards to claim, a collection of pawns to unlock in nine colours, and auras for your profile icon.

YOUR PROGRESS, YOUR WAY

No account is needed to play, including with a friend: without one, your progress stays on your device. If you wish, link your Google account to back it up online and pick it up again on another phone. It's optional, and you can delete that account at any time from within the game.

The game is free and funded by ads; the Patron pack removes forced ads, never the ones you choose to watch.
