Mega Block

There is no reel grid here. You set a stake, pick a difficulty, press Play, then press Go to drop each block onto the tower. Every block that lands adds to the multiplier on your total win, and you can cash out at any moment to bank what you have. Miss the placement or knock the stack over and the round ends there — the stake is gone and there is no consolation payout. That is the whole loop: build or bank.

Difficulty is the one setting that changes the shape of the round. InOut publishes four levels and how many blocks each one lets you stack: Easy tops out at 24 blocks, Medium at 22, Hard at 20, and Hardcore at 15. Fewer blocks means a shorter climb but a steeper one, which is why the studio lists volatility as variable rather than fixed — you set the risk yourself through the level you pick and the moment you decide to cash out.

The cash cap is the honest ceiling. Whatever multiplier the tower reaches, InOut caps the payout on a single round at 20,000 USD, and the published return is 95.5%. Autoplay sits behind the settings menu: you choose how many rounds run unattended (10 through 200) and a cashout step — 1, 3, 5, 8, 12, 16, 20 or 24 — that stops the sequence once the payout multiplier lands on it. If the browser drops mid-round, the game restores your last active round when you come back.
