About the product

Baccarat is a classic card game that is popular in Thai offline casinos. The gaming club is a room with an area of ≈20 m2, which contains 8 gaming stations and an administrator's workplace.

The player gives cash to the administrator and asks to replenish the account of the selected computer before the start of the game. The game can start after that. Withdrawals of funds are also made through the administrator.

Each cycle of the game "Baccarat" is divided into Stages - periods of 20 minutes. 20 games take place in one Stage. The dealer deals the cards, the player bets on 1 of three possible outcomes: player's victory, dealer's victory or a draw. Guessing who won - he gets back the rate +% in accordance with the odds.

An important part of the game is the Provably Fair check mechanism.

There is a printer in the locked box that prints the results of all games before the start of the Stage. At any time, the player can stop the Stage, open the box and check the results on paper with the data on the screen. A new Stage starts after opening the results.

Hardware demo


The development "from idea to implementation in the client's country" took 120 days.
Over this time:
• Created 2 versions of Provably Fair.
• Ver 1.0. - self-assembled plastic box with a lock. We put an inkjet printer inside, filled with ultraviolet paint. This implementation was abandoned due to its unpresentable appearance, lack of reliable protection of printed results, and difficulties during verification of results.
• Ver 2.0 - the system unit in which they were installed:
‣ LEDs
‣ Power Supply
‣ Magnetic locks
‣ Cash register printer
‣ Matt results box
‣ Raspberry Pi to control hardware from the admin panel
• Created a game server and administration panel.
• Created a client. A small system unit was attached to the back cover of the touchscreen. We installed this structure on a stand.
• We filmed a video with girls-dealers.
• We prepared the business for launch: we went to Thailand, installed hardware, set up, trained personnel.
• Added software licensing for expanding business via franchise
