Everyone loves an animal themed online slot game. Builder Beaver celebrates the large aquatic rodents that populate many North American forests, which are famed for their wood gnawing teeth and their dam building skills.

This slot machine from RTG gives players a number of free spin rounds complete with a high quality base-game that’s all about the play and the wins available here.

Graphically, this slot brings out the cute side of beavers, with a big dose of cartoon styling to create a casino game that’s anything but wooden.

The base-game is set in a charming river-bank style background and the beavers themselves have been given a construction worker overhaul complete with hard-hats and overalls, bringing out the industrious side of these forest creatures.

Like many other RTG slots this machine seems to call on the numerous hand-drawn cartoons of yesteryear for inspiration, with an visual appeal that you can trace back to your childhood.

When it comes to the slot sonics, Builder Beaver is sadly lacking in the contemporary sounds that have made many of its casino peers into highly playable games. There’s the standard RTG spin noise and whilst some might argue that the lack of incidental effects means that you can concentrate on the reel action, we’d like a little more bang and boom with our base-game. However, there is a noticeable ramp up in sonic effects when you find your way into the bonus round on this game with some signature blue grass fiddle and thigh slapping music that helps set the atmosphere. It’s a shame we couldn’t have this right the way through the slot.

The Builder Beaver base-game could not be simpler. There’s a load of winning potential in the twenty-five line grid that’s spread across the five reels in view. You’ve got the usual controls that allow you to adjust the wager amount per line and the number of lines on which you’re betting to create a bespoke bet with every spin.

Specials are included in this game in the form of a Builder Beaver signature wild and a special scatter symbol that holds the key to the bonus round here.

Hit three or more beaver wild symbols anywhere in view in the Builder Beaver base-game and in addition to the big combination prize you’ll probably hit, you’ll also activate the first free spin round. This takes you to a special second set of reels with 12 free games under you belt. Here the beaver wilds will now multiply the prize value of any combination in which they appear by 3x, giving a considerable boost to the winning potential of the reels.

You can even re-trigger this bonus by landing a further three wilds anywhere in view, adding a further 12 free games to your total.

The second bonus round in Builder Beaver is activated when you hit three or more of the special sign scatters anywhere in view. This takes you to an alternate reel set where you’ll receive ten free spins. Here the scatters not only pay you out for combinations of two or more anywhere on the reels, but after the scatter wins have been evaluated, these symbols turn into extra wilds, giving you extra chances to hit some big winning combinations. Again, this bonus can be re-triggered in the normal fashion.

Builder Beaver features two progressive jackpots that can be won any-time during the basic reel game on this online slot machine. All you have to do is spin the reels of this slot machine to stand a chance of winning and if you’ve won either jackpot it will be awarded immediately after your spin, regardless of any action on the reels which will pay out in the standard manner.

Slot Professor Says


Builder Beaver is an interesting slot game that provides a huge amount of base game action. I’m always one for any machine that uses wild symbols as a feature activation system as this more or less guarantees a big win on the reels to accompany the bonus trigger. Builder Beaver is one such machine and it plays incredibly well.

I could go on about how RTG titles fall behind the rest of the pack with their sights and sounds, but actually on this occasion I feel that Builder Beaver plays well into the classic casino slot machine trope. The graphics are cute and classy and reminiscent of some kind of 1950s cartoon, taking you back to the good old days and everything has a touch of the idyllic wood-side air, giving the game a relaxed atmosphere.

The two bonus games on Builder Beaver are more than enough to keep any player happy. I’ve often found with this game that the feature re-triggers seem to be set at a higher rate than on many other slots and you’ll often find yourself spinning extra spins – especially on the feature activated with three wilds as this seems to hit all the time. You’ll have a good fun time on this game, which is definitely one designed with the player in mind.
