With 6 reels and 4 rows, all the symbols become so much smaller and less attractive, so much so, the overall appearance isn't that good at all. Nothing like big very nice icons for me. Small ones are cluttering and unpleasing. The Diamond is the Wild symbol in the game, appearing only on reels 2, 3, 4 and 5, multiplies all wins by 2x, 3x or 5x randomly, and substitutes for other symbols except the Scatter symbol. What I don't like about this Wild symbol is in not paying for itself and not appearing stacked or expanded. Instead, the Buffalo symbol is stacked on all reels. 'Free Games' is the Scatter symbol, again not paying anything for itself, argh, and getting 3 or more of them awards up to 100 free spins, in the order of 8, 15, 25 and 100 free spins, depending on the number of triggering Scatters. The highest paying symbol, the Buffalo, pays a very low 300x the line bet for 6 of them, and the other symbols pay from 250x to 100x the line bet for 6 of each kind. Damn! If not for the 4096 ways to win, I would use unspeakable expletives in rating this kind of paytable! It's a blardy low one indeed.
During the Free Spins game, 2 Scatter symbols adds 5 more free spins, 3 Scatters adding 8 more, and so forth, up to adding 100 more free spins with 6 Scatters, and with an infinite number of free spins possible. This is just a marketing ploy, which can never be true of course, because the free spins just cannot go on indefinitely forever! Where Playtech is concerned, Safari Heat still holds the record for the most number of retriggering of the Free Spins games, with 20 retriggers, for an additional 300 more free spins. Other games have the same 'infinite' retriggering clause too, but they usually end within 6 retriggers. For Microgaming games, as a comparison, it is mostly 1 retrigger, but very difficult to get, or very rarely with 2 retriggers, and only once in a blue moon with 4 retriggers. Nothing more than that, as far as I know.
