Haste Rewards allows a user to earn Haste Loot, which includes free game optimization sessions. You can track your progress toward earning Haste Loot in the Haste Client and at My Account.
Players can earn up to a maximum of two Haste credits per day – just for playing Haste supported games (currently Overwatch and League of Legends) with Haste running in the background. For each gaming session you earn a credit, for 10 credits you get a Reward which you can cash in for a Haste-optimized session playing a supported game. As soon as you cash in your Reward for optimized game-play, you start earning credits again.
