🎰RTP – 99.7%

💰Max Win – 1,000x

🎢 Volatility Level – Low

best slot machines ugga bugga

If you are used to modern video slots with flashy graphics, animations, and bonus rounds, Ugga Bugga might be a bit of an adjustment when you first start out.

However, this old-school Playtech slot machine has a ton to offer, not the least of which is its impressive 99.7% RTP rate, higher than any other slot on our list.

The game’s African theme and simple set of sounds and graphics actually make for an enjoyable gameplay experience as well, although the game runs a bit slow compared to some of the more modern slots out there.

The game's mechanics are unique, allowing you to spin the single three-symbol payline once, hold your favorite symbols, and then re-spin them on all ten of the game’s paylines.

This can make for some amazing winning spins, as well as many break-even spins, which reduces the volatility and allows you to play for higher stakes than you could normally.

If you haven’t had a chance to try Ugga Bugga earlier, give it a shot and find out for yourself why we placed it on our list of best slot machines to play at the casino.

Like most “book” slots, Book of 99 activates free spins when three book symbols appear on the grid, but that is not all.
