Kitty Glitter Slot
The Kitty Glitter slot from IGT bears obvious similarities to the Cats slot but has totally different gameplay. Like the IGT Star Trek game, it has a free spins bonus which is triggered by getting the bonus Symbol on reels 2, 3 and 4 simultaneously but the feature itself is quite unique.
The free spins bonus awards 15 free spins and during these you collect Diamonds on Reel 5 which accumulate to make extra kittens wild symbols during the remaining spins. Every 3 diamonds makes an extra Kitty wild. When you throw in the fact that Kitty Glitter also has stacked symbols, the bonus feature can be quite rewarding. Without the free psins feature however, like other IGT slot games, it is quite difficult (though not impossible) to walk away with a profit.
I see Kitty Glitter frequently at land-based casinos over here in the UK but it doesn't strike me as popular as games like Rainbow Riches, the Cleopatra slot or Novomatic's excellent but dangerous Book Of Ra Deluxe. It may be because it has an old-skool feel to it or maybe because triggering the feature is quite tricky but nonetheless it's a decent enough slot machine. The payout percentage of the online version is better than the land-based at a shade under 95% although it's tricky to see why - probably the reel strips differ slightly.
Kitty Glitter is available at several online casinos that licence games from IGT such as BGO Slots but also Paddy Power and Virgin Casino all of which are reviewed here at slots.org.uk and come recommended by me (I play at both!).
