MonoBet is a demo project made for fun. Marks (Ɱ) are virtual play money with no monetary value — they cannot be bought, sold, deposited, or withdrawn. This is not a real prediction market, betting service, or financial product.

Play money only. Not financial advice — not even real money.

Terms of Use

The short version: this is a toy. Have fun.

Made for fun, not for real

MonoBet is a personal demo project built for entertainment. Nothing here is a real prediction market, betting service, exchange, or financial product. Market outcomes, prices, and payouts are simulated by software.

Virtual Marks only

Marks (Ɱ) are virtual play money. They have no monetary value and cannot be bought, sold, deposited, withdrawn, exchanged, or redeemed for anything. Winning or losing Marks means nothing outside this site.

Accounts

Accounts are identified by username and password; an email is optional. Passwords are stored hashed. Accounts may be suspended or deleted at any time, for any reason — including wiping the whole database on a whim.

Fair play

Do not create markets or post content that is illegal, hateful, or harassing. Do not exploit bugs to print Marks — it is play money anyway. Admins can edit, resolve, or delete any market or comment.

No promises

The site is provided as-is, with no warranty of any kind. Balances, markets, comments, and accounts can be wiped or reset at any time without notice. The project may change or disappear entirely.

Open source

MonoBet is open source under the MIT license. Questions or issues: github.com/Dvorinka/monobet.
