We don't have enough impressions about the amount of rotation that triggers a free spin or reward. Before the bonus is finally offered, we are spinning and it seems to be eternal.
When playing a bonus game, we found it to be very basic and didn't really provide much in terms of cash or excitement. Our bonus round is too fast, cost us 10.00 to enter, we can only accumulate 5.00.
Use the control panel below the reel to adjust your bet and start the reel rotation. It is not necessary to click the spin button to turn these reels, as you can press the space bar to rotate faster.
