Vault Blast Hold & Win

If you like your slots with a clean, punchy setup and a standout bonus mechanic, Vault Blast Hold & Win by Octoplay is built for you. Found in the online slots Ontario catalogue, this online slot title runs on 5 reels, 4 rows, and 20 paylines, with a max win of up to 3,000x your stake. Just as importantly, the whole game is designed around one core mechanic: land enough Bomb symbols, lock them down, and let the vault do the rest.

Hold & Win trigger: Land 6+ Bomb symbols in a single spin to start the Hold & Win feature with 3 lives. Bombs lock in place, and your lives reset whenever a new Bomb lands.

Vault reveals at the end: When the feature ends, each locked Bomb opens the vault behind it, revealing one of several outcomes:

Cash prizes: Vaults can reveal cash values from 1x up to 25x your stake, and individual cash prizes can reach up to 1,000x.

Double Crown: Doubles all previously revealed cash prizes.

Raccoon collector: Can appear up to twice and awards a cash prize equal to the total of previously revealed cash prizes.
