Personal testers opinion
The prize pool at Doubles slot machine is distributed in this way: 80% is paid in the main game, and 20% is reserved for bonus spins. My most significant winning was only 35x in usual spins. You should pay attention that during the testing I made 10,000 spins. And the average payout from the bonus did not exceed 11x. The slot is great for completing the bonus requirements (7,68 out of 10.)

Description of the slot machine
