Rush is a card game.
While time is running down, play as many cards as possible. Gain points and time boni for every turn.
Score as many points as possible and compare your highscore to others via the GameCenter.

Simple Rules:
Tap one of your card piles, to play a card. Card values reach from 1 to 13. You can play a card, when its value
is one higher or one lower than the card on the discard pile. For example, you can play the 7-card on a 8 or a 6.
Additionally, a 13 fits on a 1 and vice versa.
When you can't play a card anymore, just tap the closed pile on the right hand side to receive new cards.

The app is free, but contains advertisment. You may upgrade the app and enjoy Rush free of ads.
