Apollo 77 Slot: Demo Play, Review, Casinos List

Apollo 77 is a Smartsoft 0 fixed betlines, Medium-low variance product, which includes a RTP of 96.0 % and x250 as the maximum win (published on July 26, 2019). Those are the features of this slot: Bonus game, Wild, Buy bonus feature.

Mission Checklist

Smartsoft rolled out Apollo 77 on 26 July 2019, and the theme is pure space fandom rather than hardcore science‑fiction. Five transparent reels float over a starry backdrop while a gentle cosmic hum fills the speakers. Instead of fixed lines the slot uses an “adjacent reels” engine, so technically there are 0 pay‑lines—any three‑of‑a‑kind starting from the left reel pays, which keeps the screen clean and makes wins easy to spot. Bets start at 0.25 € and max out at 100 €, ideal if you flip between cautious test runs and full‑throttle sessions.

Symbol design sticks to the Apollo name: the letters A‑P‑O‑L plus a glowing 7 handle the low tier. They look humble, yet when five identical letters align you still bank twice your stake. Premiums include a satellite dish, shiny astronaut helmet, lunar rover, orbiting station, and the footprint next to a planted flag. That last one is the champ at 40× bet for five adjacent hits, although that headline figure feels toned‑down compared with modern high‑variance titles. Mobile play runs just as smooth as desktop; I’ve spun dozens of rounds on an aging Android handset without lag.

Cabin Systems Overview

A sliced rocket emblem acts as the Wild, swapping into any regular symbol to finish a combo and sparking a minor jet‑engine audio cue each time it helps out. Base‑game visuals are bright but not overwhelming; reels glow subtly rather than flashing garishly, so the slot suits longer sessions. Top win is only x250 total stake, and that can’t be stretched by multipliers because the math model omits them. Payouts travel left‑to‑right only, so don’t expect Win‑Both‑Ways surprises. Still, I do appreciate the auto‑spin panel with adjustable stop‑loss and single‑win caps—it speeds up grindy stretches while keeping my bankroll under control.

Clicking the ship icon at the right edge toggles a side mission: every time you land a prize containing any of the letters A‑P‑O‑L‑7, that letter lights up on the hull. Fill the entire inscription and the craft blasts off, awarding an instant cash prize based on flight distance. It isn’t huge (my best was 18× bet), though it breaks monotony nicely between bonus rounds.

Fuel Consumption And Flight Stability

At exactly 96 %, Apollo 77’s published RTP is honest but unspectacular; plenty of contemporary releases hover at the same level. Because Smartsoft doesn’t sell variable RTP packages, you don’t have to waste time double‑checking what version a casino runs. The math sits in the medium volatility pocket—hit frequency is decent, but stretches of dead spins still pop up if you push turbo mode. With that in mind I recommend a buffer of around 150 to 200 wagers, so an average €1 spinner might load €200 before blasting off. Players who chase one monster jackpot should probably look elsewhere; this mission is about steady oxygen rather than dramatic supernovas.

Docking Mini‑Slot Bonus

Hitting three or more bonus icons opens a separate three‑reel, single‑row console. The number of bonus symbols translates into attempts:
• 3 bonus icons → one spin of the console
• 4 bonus icons → two spins
• 5 bonus icons → three spins

Before each spin you pick one of the eight cargo symbols displayed underneath. The reel then spins; if the arrow stops above your chosen cargo, you receive a prize between 2× and 100× total bet and the symbol locks. Stop on an “Exit” wedge and you lose a try. In my own test runs, the mini‑slot usually paid 8 ‑ 20×, but twice I snagged the 50× rover crate, so luck swings hard. Visually it reminds me of an old arcade crane game, complete with bleepy sound effects, and it definitely hits the nostalgia spot.

Emergency Thrusters Purchase

Impatient orbiters can bypass the grind and activate either bonus instantly via the bright orange Buy Bonus game button beneath the reels. The cheaper package costs 35× stake for a three‑symbol bonus, while the deluxe ticket asks 70× and guarantees at least four bonus icons. I’ve bought the cheaper deal a handful of times; mathematically it sits close to the long‑run RTP, yet there’s obvious variance—expect occasional single‑digit returns next to flashy 60× bursts. If your bankroll is thin, I’d avoid spamming purchases, but grabbing one when the letters side‑mission is nearly filled can be a clever hedge.

Auxiliary Systems

• Wild symbol: The rocket wild appears on all reels and substitutes for every pay symbol. It slides into place with a tiny swoosh animation that adds a bit of atmosphere without dragging spin time.

• Double‑up Feature: After any standard win (not during bonuses) you can gamble via a red‑versus‑black card. Tie results let you retry for free, a rare friendly tweak. I like using it after tiny letter wins; losing doesn’t hurt, winning doubles up the flight fund.

• Auto‑spin with loss limits: You can queue infinite rounds but stop them when cumulative losses pass a figure you set. Not every indie studio bothers adding that safeguard.

• Spaceship Inscription Meter: Lighting A‑P‑O‑L‑7 letters during base hits eventually triggers an instant‑cash animation. Rewards range from 5× to 25× stake based on distance covered. Small money, yet psychologically pleasing.
