Novomatic's Sizzling Hot slot is one of the most popular Gaminator-based land slot machines in Europe and has a real cult following in continental Europe in particular. The old version has been superceded by a Deluxe version which isn't a great deal different and the latter is the version you will find in online casinos.
Along with Roaring Forties and Book Of Ra Deluxe it is also a popular game in South America where it appears, along with the other two, on Novostar machines in land-based casinos, especially in Argentina, Chile and Uruguay.
Sizzlin Hot Deluxe is actually quite a basic game with no real feature to talk of but it is one of those games that can dish out big rewards and it's quirky implementation does have something rather endearing about it. Other games like Power Stars and Ultra Hot are very similar in style but have never quite gained the popularity of Sizzling Hot even though I personaly prefer them myself.
