Like Far Cry 3 before it, the upcoming Far Cry 4 now has a companion app that will interact with the main title once it's out.
It's actually a standalone poker game with puzzle elements, which you can play to earn in-game currency for the PC or console version of Far Cry 4.
In the game, you form a five card hand from cards falling from the top of the screen. As the cards descend, you can tap on them to change their face.
Cards shuffle randomly with each tap, making each shot at a better value a gamble.
Once the card reaches the bottom, it's added to your hand, which is rewarded once you have a full five card hand.
Far Cry 4 Arcade Poker is a free download, with in-app purchases that grant you extra coins or special items to use in the game.
