Press Play demo, choose an entry of $5, $10 or $20 and a skin, then press Play. The round starts after a short countdown.

Timed competitions with a shared leaderboard and prize pool. Not built yet: we would design it together with an operator.
A special arena objective: carry the ball and survive. Not built yet, and its rules would depend on the operator and local regulation.
We aim to take ViperCoil into official, licensed casino lobbies as an instant game. That needs maths and RTP design, lab certification and wallet integration. We are looking for funding and partners to do it: game providers, studios and private investors.

What these numbers do not show. They describe the market, not ViperCoil. We have found no licensed casino game in the snake arena style yet; showing that one can sit in a lobby is the task ahead, and we want to do it with a partner.
ViperCoil itself is a free demo. If you are 18 or older, you can look at real-money games at a third-party casino. ViperCoil is not available there.

In a casino lobby, players pay an entry for each round and the casino and ViperCoil share a small fee. The 10% fee and the 90/10 split below are example assumptions, not agreed terms. They are illustrations, not forecasts, and no earnings are guaranteed.
Our goal is to take ViperCoil into official, licensed casino lobbies. We have a playable game and are looking for funding and partners to cover the route.
Illustrative split only. The final operator agreement will define the fee and revenue allocation.
This model counts entry fees only. Elimination fees and progressive rake are not simulated. Change the assumptions in the calculator below.
Illustrative arithmetic only. These are not forecasts or ViperCoil earnings.
Illustrative only: adjust the assumptions to see entry volume and nominal fees. The calculator runs in your browser and sends nothing anywhere.
