CryptoColosseum is a layered game. We call it "a crypto game of degenerate gambling and whimsical violence." Gladiators (NFTs) fight in the arena. It's easy to get started, but difficult to master. It's a game of expected value, cash flow, markets and collecting.
Gladiators belong to factions (BTC, ETH, MATIC) and the price movement of those assets effects the outcome. Players buy items which help their gladiators or hurt their foes. Gladiators win a percentage of the prize pool and factions win pieces of the gladiators take too.
You end up with a game that you can get started by just betting on a gladiator you like... and then, if you want, you can get really deep into the crypto-economics and market forces... all the way from yield generation to governance.
And that's just the game play. Items are NFTs and some will be very collectible. The gladiators themselves are NFTs and they offer unique characteristics that differ from other pure collectibles.
