#NOTCOİN is a free to play Play-to‑Earn (#P2E ) game built into Telegram, created by the Open Builders team and integrated with the TON (The Open Network) blockchain. Launched on January 1, 2024, the game allows users to earn in game points known as "Notcoins" by tapping a virtual coin in a chat, which can later be converted into actual $NOT tokens.

The gameplay is enhanced with features like energy limits, power ups, league progression, missions, #NFT vouchers, and even team competitions to keep engagement high.
