One spin, priced

The unit of spend in Bob Marlin Goes Deep is the spin — stake, reels, result, repeat. It runs on a 5x4-7 grid and ways-to-win wins. Ways-to-win pays matching symbols on adjacent reels from the left, wherever they sit. Whatever the visuals do, you are charged per spin, not per second; speed settings change the pacing you experience, never the price you pay.
