From within the game, you can check the last 10 games you've played in the casino. To do so, go to the "Clock symbol" or "Game history" tabs by clicking on the "Settings" section in the game's corner.

You can see the last 10 bets you made on the game, as well as the details of those bets, here. The details in this section may differ according to the games. While some games display the symbols that appear as a result of the bet, others only display the game name, bet amount, and so on.
