2027 Iss — slot review and demo

Space station and game symbols in 2027 ISS

Endorphina released the slot to mark the anniversary of humanity's first spaceflight. The reels feature classic casino attributes in a futuristic design: roulette, dice, slot machines. Wild in the form of a female astronaut substitutes all symbols except Scatter, Fuel and Hyper Space Jump, and pays 1000× the bet for a combination of five Wilds. Roulette is the highest regular symbol with a payout of 83× for five in a line. Scatter featuring the ISS station triggers the bonus round.

Unlimited free spins with fuel cells

Three or more Scatters in any position activate unlimited free spins mode with a starting reserve of three fuel cells. All wins in the mode are multiplied by 3. The Fuel symbol adds one cell to the counter and pays 2× the total bet, while the Hyper Space Jump symbol consumes one cell and pays the same 2×. Both symbols appear randomly. Free spins continue as long as at least one cell remains on the counter — theoretically the round can last indefinitely if fuel is replenished faster than it is consumed.

Specifications and bet range

The slot's RTP is 96.06%, volatility is medium-high. The bet range is from 0.01 to 1 per line, giving a total range from 0.09 to 9 per spin with nine active paylines. Five Scatters pay 500× the base bet. The game features a classic gamble feature and Bonus Pop function (depending on operator jurisdiction).
