Not all games show a popup after the redemption, in some games there is only a sound and credits are counted up, in some games there is nothing, for example you only get a letter in the in game mailbox with the reward.
It happens that a Reward Link is not redeemed the first time, after a while there is no reaction from the game, it often helps to try it several times, this problem is usually caused by the game server itself, for example if too many links are redeemed by other players at the same time.
Usually a popup appears in the game with a message like 25 Spins Written Well. Click on the link you want to redeem, the link will open automatically. To redeem the Reward Links restart your game, wait until everything is loaded.
