The free chest board

A chest board in the world reads FREE CHEST with the condition LIKE GAME AND JOIN GROUP. It is the game's most literal free reward: meet the two social conditions and the board pays out without any gameplay requirement.

It is also the only repeatable free reward confirmed in footage, which makes it the first stop of every session. If the board shows as locked, check that your Roblox account has liked the game and joined the developer's group — the game checks both.

Codes: the biggest single payout

Five cross-verified codes are live right now, and the rewards are front-loaded for new accounts: COMMUNITY alone hands out 1,000 cash plus a Small Engine and a Small Tank — two of the six core build slots.

Codes are usually one-time per account and do not expire on a fixed schedule — the developer edits the same community message when new ones drop — so the honest strategy is to redeem the full list on day one and re-check after every update. The codes page tracks this with a last-checked date.

Event tokens and limited rewards

The Hacker Event ran through September 2026 with its own currency, Hacker Tokens, handed out by two of the current codes (HACKER gives 50, 1x1x1x1 gives 150). Event currencies only matter during their window — if a new event appears on the world board, treat its tokens as a use-it-while-it-lasts resource.

Scheduled events like the admin-abuse nights also carry rewards; signing up from the world board costs nothing and the game confirms with a message.

Global boosters: free multipliers

The world's Global Booster panel runs timed multipliers with a reset countdown — one observed booster showed 10K with a reset timer. Boosters are free and server-wide, and they stack with everything else you own.

The optimal free-play pattern: bank a run inside a booster window, then spend the winnings during the same window while luck is highest.

Like and follower milestones

The game's code history shows the pattern clearly: the first batch dropped during the breakout week, and codes tend to accompany social milestones, updates, and fixes.

That makes the community channels the highest-value free subscription in the game — following the social links the codes panel points to is how new drops arrive without checking third-party sites.

FAQ

Free Chest and Rewards Guide FAQ

How do I get the free chest?

Like the game and join the developer's group, then collect from the FREE CHEST board in the world. Both conditions are checked together — one of them missing keeps it locked.

Do codes expire?

They can, but they are not on a fixed timer — the developer edits an existing message rather than announcing each drop. The codes page only lists codes after cross-verification and marks the last-checked date at the top.

What are the best free rewards for a new account?

The five current codes (cash and parts), the free chest, and any live event tokens. Together they cover the first hour of progress without a single run.
