There are two main types of gameplay styles in 52 Card Pick-up, Frenzy and Challenge mode.
Frenzy mode is selected by tapping the large card in the upper half of the lobby. During frenzy mode, you will play through several rounds of 10-second games. With the exception of Joker’s Remix, the games are chosen from the 6 challenge mode games in that world. Completion games must be solved within 10 seconds and survival games must be survived for 10 seconds.
The goal of challenge mode is to earn stars and a high score in each game. Completion games challenge you to finish as fast as possible and survival games challenge you to keep playing without making a mistake as long as possible. Each challenge mode has 3 levels of performance, each earning an additional star when met.
