So, if a bubble hits a Logo in the middle six positions, it will expand to nine bubbles. In the Atlantic City play, the games started with bubbles in reels 1 and 4 and were in Bubble Burst mode.Īnother important rule is that if a bubble hits what I'll call the Logo symbol, it expands to every position on the screen next to it, including diagonally. As with regular bubbles, they bubble-up one row at a time. In Bubble Burst mode, randomly extra bubbles will burst onto the screen. The second I'll call the 'Bubble Burst' mode. To make matters more complicated, there are two modes to the game.
