There's some probability/non-zero chance that there is going to be an airdrop coming, especially if the builders of the game want more growth.
Because nothing is free, then they will need to buy for that growth, and offer an incentive for people to play the game. In crypto, it's easy. - Announce an airdrop.
Actually its depend on the owner of the project. Its hard to say when a platform will do an incentivized tokens later or not. Normally a project has a roadmap and whitepaper discussing some of these but when I browse the website theres no discussion about that.
But this type normally shared before a platform got a working product but this one is active now and working. Means werent sure, but considerung being noncustodial approach via solana wallet. They can actually have if they want.
Anyway the purpose is to use the platform and enjoy its style of gambling in any case they incentivize users by an airdrop thats only an added bonus to anyone.
