# Gamba > Build on-chain games on Solana Gamba provides tools for building and playing provably fair games directly on the Solana blockchain. Gamba functions as a decentralized gambleFi protocol for on-chain betting games on Solana. It enables developers to create betting applications with zero backend deployments, allowing users to earn fees on player activity. Gamba uses provably fair random number generation and provides liquidity pools for various tokens.
