Space Zoo

Space Zoo is an outer space slot from Backseat Gaming, built on the Hacksaw Gaming OpenRGS platform. Load it up and you will find a 5-reel, 4-row grid framed in futuristic metal, with 14 paylines running across it. The setting places zoo animals in spacesuits drifting through the cosmos, with distant sound effects and hovering objects filling out the backdrop. Stakes run from 0.10 up to 100 per spin.

Notice how the visuals lean more quirky than cinematic. The graphics are neat rather than spectacular, but the charm comes from the theme itself. Expect medium volatility rated 3 out of 5, a default RTP of 96.22%, and a maximum win capped at 10,000x the bet. Keep in mind a lower RTP version of 94.29% exists at some operators, so check before you play.

Look at the paytable and you will spot two tiers. The lower-paying symbols are the standard card ranks from 10 through A, each returning just 1x your bet for a five-of-a-kind line. The higher-paying symbols are where things get interesting. Giraffes, lions, elephants, and zebras appear in their space gear, paying between 10x and 12.5x the bet for a full line of five.

Keep an eye on the Wild symbol, which lands on all reels and substitutes for every regular pay symbol. A winning line of five Wilds pays 20x the stake, making it the single most valuable symbol on the reels. You will also see a Wheel of Fortune symbol and Scatter symbols. These do not pay directly but act as gateways into the feature set.

The Wheel of Fortune symbol is the engine driving most of the action in Space Zoo. When one lands, look for the number attached to it, ranging from 1 to 3. That number tells you how many spins of the wheel you receive. Each spin awards a modifier: randomly placed Wilds (2 to 10), a Symbol Upgrade that converts all low-pay icons into a single high-pay symbol, a Global Multiplier of x2, x3, or x5, or Cash Prizes hidden behind reel positions with values from 2x up to 1,000x. After the modifier plays out, the Wheel of Fortune symbol itself turns into a Wild. In the base game, multipliers and cash prizes apply to the current spin only.

Land 3, 4, or 5 Scatter symbols in a single spin and you trigger the Free Spins bonus, awarding 10, 12, or 14 spins respectively. This is where the game opens up. Notice how the Wheel of Fortune triggers more frequently during free spins, and crucially, Global Multipliers and uncollected Cash Prizes now persist for the entire round rather than vanishing after one spin. Cash Prizes sit in place until a winning combination passes through their position, then they are collected and disappear. The wheel can also award 2 to 5 extra free spins, extending the round further. Scatters do not appear during free spins, so retriggering through the normal route is off the table.

If you prefer to skip the wait, Space Zoo offers three bonus buy routes, all flagged as highly volatile. The cheapest is BonusHunt FeatureSpins at 2x your bet, which makes each spin three times more likely to trigger the bonus game. At 50x the bet, Wheel of Fortune FeatureSpins guarantee a Wheel of Fortune activation on every spin. The most direct path costs 100x the bet and drops you straight into the Free Spins round with 10, 12, or 14 spins. Note that the top prize of 10,000x is only achievable through the Wheel of Fortune FeatureSpins or the bonus game, not during standard base game play.

Space Zoo from Backseat Gaming does not try to overwhelm you with complex mechanics or flashy production. Instead, it relies on a single well-implemented feature, the Wheel of Fortune, which ties together Wilds, multipliers, cash prizes, and symbol upgrades in a way that keeps sessions moving. The free spins round is where persistent multipliers and sticky cash prizes combine for the best results, and the FeatureSpins at 2x offer a low-cost way to speed up your route there. A solid, straightforward slot with enough going on beneath its quirky surface.
