About this app
Stack Jack is a fast card race. Flip, stack, and clear the pile before anyone else does. Rounds take a couple of minutes, and the difference between winning and losing is usually half a second. PLAY WITH FRIENDS Create a room, share the code or the link, and start. Up to a full table, no accounts, no setup. Anyone who taps your invitation lands straight in the room. PLAY ALONE Bots at every difficulty, including one that will genuinely beat you. Practice a shuffle, learn the timing, then take it back to the table. CLIMB THE LEADERBOARD Every round counts toward the season. Track your wins, your fastest clears, and where you land against everyone else. Seasons reset, so a bad week is only a bad week. UNLOCK CARD BACKS Keep playing and keep collecting. Cosmetic only, nothing that helps you win. LEARN IN A MINUTE A short tutorial walks you through your first round. After that it is all reflex.
