Sonic Arcade is a key component of Sonic Labs's incentivized testnet campaign, designed to drive early growth on Sonic by encouraging users to interact with the Sonic testnet by playing various free-to-play games.
This marks the first opportunity for users to earn points for the S token airdrop by playing games.
Points earned by playing the various free-to-play games available, such as Plinko, Mines, and Wheel, are called Arcade Points.
These points are part of the S token airdrop.
To participate on Sonic Arcade, you need $TOKEN to play, and each game costs 1 $TOKEN. You can claim 210 of them for free weekly.
Note that $TOKEN has no monetary value — it's just for playing games on Sonic Arcade.
