There aren't many stone-age themed games around, and the few that are available for play aren't that good either, regardless of the software it comes from. This caveman themed game is one of those stone-age games, named Wooly World, in reference to the wooly animals of that time, but only the Caveman, the Axe and the Mammoth elephant icons are relevant, all the other icons in the game could be from another later period in time. Nonetheless, the overall appearance and presentation of this Wooly World game is not too bad, still better than most other similar oldie games.
The Caveman is the Wild symbol, appearing only on reels 2 and 4, it doesn't pay anything for itself, dumb symbol, but pays 4x for all wins with it, including substituting for other symbols except the Scatter symbol. The logo 'Wooly World' is the Scatter symbol, paying 200x the total bet for getting 5 of them, and getting 3 or more of the Scatter symbols trigger the Free Spins game. Pick 3 of the 5 frozen animals to reveal the number of free spins. All wins during the free spins are doubled, and the Free Spins game can be retriggered. As for the other symbols, the Tiger pays 5000x, the Elephant pays 2500x, the Beaver pays 1500x, the Compass pays 1000x, and the rest pay from 200x to 100x, all per line bet for getting 5 of each kind. A good paytable.
Well, I was interested to see how this Wooly World game would play and pay, because I haven't played it before. The game looks okay enough, I quite like the colours used in the game, and the icons look cool and pleasant. But the game was still in the stone age for me, literally, because nothing came spin after spin, only very small insignificant payouts, which were actually losses when compared to my bet amount. After spinning 200 spins with not a single Free Spins game or any single good payout, I quit playing Wooly World, knowing well enough as to how most of Microgaming games would go whenever it starts cold. Another very disappointing game for me.
