Double Up: Card Money Battle

Grab cards, grow your stack, beat every rival.

Double Up is a fast, addictive card duel about one thing: ending each round with more money than your opponent.

Win rock-paper-scissors to pick first, then grab from a table of cards that grow your stack — or wreck theirs. Bank the biggest cash cards, chain multipliers when you're ahead, and hurl steal, bomb, and swap cards across the table when you're behind. Every round the cards rearrange into a new shape, so no two hands feel the same.

GROW YOUR EMPIRE Bank your winnings into real estate around the world — from an Austin food truck to an orbital space hotel — and stock a vault of jewelry that boosts every payout. Merge duplicate pieces into higher tiers and never hit a dead end.

KNOW YOUR RIVALS Face eight opponents who each play differently — the greedy, the cautious, the ruthless, a card-counting grandma, a magician who flips the table face-down, and a rival who studies and copies your own habits. Then take on the boss chain: The Banker, The Auditor, The Chairman, and The Vault, each with brutal twists and huge rewards.

FIVE WAYS TO PLAY

• Classic: climb the levels and build your net worth
• Tournament: pay in, win three straight, take the pot
• Heist: hit a cash target while security fights back
• Daily Challenge: one seeded deck a day, double rewards
• Endless Gauntlet: one stack, how far can you push it
• Pass & Play: two players, one phone

No ads. No real-money gambling. Just you, the cards, and the drive to double up.
