Wolf Run, Siberian Storm and the Glitter Cats

Three IGT games show how the company thinks about slots: simple screens, one strong feature and a theme you recognise from across the room.

Wolf Run went online in 2014. It plays on 5 reels and 4 rows with 40 lines, and its howling wolf wilds come stacked, which is where most of the action is. Three bonus symbols on the middle reels start 5 free spins, and SlotCatalog says they can retrigger all the way to 255. Siberian Storm is the odd one out with its 3, 4, 5, 4, 3 layout and IGT’s MultiWay Xtra system, 720 ways that pay in both directions, with free spins started by five or more tiger’s eye symbols.

Kitty Glitter, a 30 line cat slot, has been a land based favourite for more than 20 years, and in July 2025 Kitty Glitter Grand added a wheel bonus and random wilds. Caesars launched it online and in its Atlantic City casinos at the same time, which the release called IGT’s first simultaneous exclusive launch in the US. If these older, cleaner designs appeal to you, our slots section has plenty more to compare.

IGT Casinos and the Return You Actually Get

Here is the catch with a lot of floor classics. Many of them sit below the 96% that players often use as a rough benchmark, and some exist in more than one RTP version. These are the figures SlotCatalog lists:

A point or two of RTP sounds small, but over a long session it adds up. The same game can also run at a different setting in different IGT casinos, so the figure in the table is a starting point, not a promise. Open the help screen of the slot at the casino you actually use and read the number there.
