Nimbo Play runs on Solana devnet. Devnet SOL is a free test token with no monetary value. Nothing you win here can be sold or exchanged, and nothing you lose costs you money. Treat every number on this site as a test number.

​
The short version

Nimbo Arena is a real-time arcade game in the spirit of slither.io. You stake SOL to enter, your snake spawns with a size proportional to what you staked, and you grow by eating — pellets, boost trails, and the corpses of players who died. The catch is the exit. Growing is not winning. The only way to turn what you are carrying back into SOL is to reach an extraction point and hold it for 12 seconds, fully visible and fully vulnerable. Die before that, and everything you carried drops to the floor for someone else. Nimbo Play is the umbrella; Nimbo Arena is the first game on it.

​
What this is not

Not a casino

You never play against the house. Every lamport you can win came from another player’s stake. There is no random draw, no dealer, and no house edge on the outcome — only a flat fee on entry.

Not pay-to-win

Cosmetic skins are planned. They will stay cosmetic. Staking more makes you bigger, which is as much a liability as an advantage — a large snake is slower to turn and worth more to whoever kills it.

Not an investment

There is no yield, no return, and no promise of profit. The arena is zero-sum before the entry fee, and negative-sum after it. Most players should expect to lose their stake.

Not fully on-chain

The gameplay runs on our servers, not on Solana. This is a deliberate trade-off and it has consequences you should understand before staking — see Trust model.

​
Where the money actually lives

Your stake is not held by us in a company wallet. It goes into a Vault, a program-derived account on Solana that has no private key. Nobody — including us — can move funds out of it except through the arena program’s own rules. What the program will not let us do, even if our servers were fully compromised:
  • pay out more than the vault actually holds;
  • pay the same extraction twice;
  • close a round early to freeze extractions that are still pending.
What it does let us do is decide how much you extracted, because the game itself is off-chain. That is the honest limit of the design, and Trust model explains it in full rather than burying it.
