You can get lucky on the Slot Machine!
The number of coins you win is calculated according to the paytable; its button is located at the bottom left side of the slot game screen.
If you bet 500 coins and win 400 coins, you’ve earned 400 coins and lost 100 coins.
If you bet 500 and win 1,000 you have earned 500 more coins than you had before the spin.
