The name of the game in question is “Tower of Pizza” slot and a maximum win for any spin of $2,500,000 sounds like a great potential to generate profits.
The two highest paid symbols in the game have prizes of 5,000 and 1,000 times your bet per line if you get a line of 5 of a kind with them, values which can amount to 15,000 and 3,000 respectively in case a wild symbol gets involved in such combination, and the reason for this is that wild symbol, depicted with a tower made of pizza, it has the power to triple your winnings whenever it replaces one of the regular symbols of the game; it is a very strong wild compared to current standards.
Inclusive it is not even necessary to form a line of 5 of a kind for getting a payout of 3,000x your bet per line in this slot; I have personally come to get several hits with payouts between 500 and 3,100 times my bet per line during a single spin, I got this by obtaining two “towers of pizza wilds” simultaneously on reels 2 and 3 in the round of free spins, and that big win is because during this round wilds expand through the entire reel.
Sometimes I finished my round of free spins with quite modest total earnings, but that does not normally worry me as this feature happens relatively frequently, or at least that has been my impression so far. I just wanted to make clear that this is a completely new game for me and I would not want to raise too high expectations on new players to avoid possible disappointments.
For my part, I think “Tower of Pizza” is a video slot that I will keep playing to see its real potential in the long run. For now, I'll just say it is a slot that you should try out.
