I made a small deposit to Buzzluck couple days ago, and played the heat is on game. I hit a big play on this game unexpectedly. I had the bonus round where I could choose a window 4 times and each success chosen window would give me some free spins and sometimes +1 or +2 multiplier.
I had 25 free spins with 4X multiplier for the bonus round, then two sirens and a fireman came out which gave me extra 15 free spins for the total of 39 free spins with 4X multiplier. The big play came in where I two firemen came out during the free spins in which the firemen served as expanded wilds (see screen shot).
I ended up winning almost $500 on this game, but I didn't want to make a withdrawal until I lost it all back. Sad ending, but that was what I used to get for being greedy lately.
