Kroup

Kroup is the training app designed for dealers, dealer school students, and anyone who wants to master the calculations and reading of casino games.

No betting, no luck: just practice, calculation, and precision. Progress at your own pace, from beginner to professional speed.

THREE GAMES, SEVEN DIFFICULTY LEVELS

Roulette — Calculate chip payouts (straight up, split, corner, street, six-line), convert to euros, and practice marking numbers on the betting layout.

Blackjack — Take control of the house, adjust the betting layout like a pro, and master the 3:2 payout in a snap.

Poker — Texas Hold'em: read the board, identify the pot winner, and hone your eye for combinations.

DESIGNED FOR PROGRESS

Each game offers exercises spread across 7 levels, from learning the basics to the most challenging situations. Track your progress: success rate, average response time, best scores, and level achieved for each game.

SIMPLE, SERIOUS, DISTRACTION-FREE

Kroup works entirely on your device. No account creation, no ads, no data collection. Just you and your training.

FREE AND UNLIMITED

Train for free every day. For unlimited access to all exercises and levels, upgrade to a Kroup Unlimited subscription—monthly or annually.

Kroup is a training tool. It is not a gambling game: no real money is wagered, no winnings are possible.
