At all points, you can see the next three cards from the draw pile. You then swipe away unwanted cards from your hand with the aim of those remaining and any newcomers forming a poker hand, which then vanishes, automatically bringing in more new cards.
When possible, you want to score ‘combos’, through multiple hands subsequently occurring with you doing nothing at all. Naturally, this requires a little luck, but there’s also plenty of skill here, in terms of managing your cards and figuring out what’s coming in the pile.
It sounds confusing, but give it time and it’ll dig into your very soul.
For free, you generously get the entire main single-deck game, which rapidly becomes furiously addictive. Splash out for the one-off IAP ($1.99/£1.99/AU$2.99) and you unlock double-deck mode and alternate card designs, along with getting rid of occasional ads.
