# Building on onchain <> IRL primitive

Checkin enables an onchain <> geolocation primitive that unlocks gameplay mechanics like Monopoly, Treasure Hunts etc. that can be open to any developers or projects that want to incorporate checkin and location data.&#x20;

Our philosophy is to generally build the game and game mechanics first to experiment and refine, and later enable others to build using the existing game mechanics.&#x20;
