What on Earth Slots
What on Earth is a space-themed 5-reel, 9-payline video slot with a wink and a wink at interplanetary oddities. Bright planets, quirky icons, and two bonus rounds give this title plenty of flavor, while the simple payline structure keeps spins fast and approachable. If you like compact gameplay that still serves up surprise features, this game delivers a fun ride without overcomplicating things.
Visuals and sound that sell the theme
The presentation leans cartoonish and colorful, with oversized planets and cheeky symbols that feel more playful than realistic. Animations pop when wins land, and small sound cues — whooshes, beeps, and a spacey synth — help reinforce each win without drowning out the experience. Background graphics are clear and uncluttered, so you’ll always know what’s happening on the reels, and the audio does a good job of building momentum when bonus rounds appear.
How the game works — reels, pays, and symbols explained
This title uses five reels and nine fixed paylines, and you can set coins per line from 1 to 5. Coin sizes include $0.01, $0.02, $0.05, $0.10, $0.20, $0.25, $0.50, and $1, giving a lot of flexibility for different bankrolls. Symbols follow the space theme: "What on Earth," Watermelon Planet, Port Hole, Plum Saturn, Asteroid, Cherry Comet, Console, and Orange Sun. The scatter icons are Rocket, Saucer, and Shuttle, and they’re the ones to watch for bonus triggers. Payouts are awarded per active payline, and matching combinations pay left to right unless the game’s pay table states otherwise.
Betting range, RTP, and how volatility shapes your session
With coin values and up to five coins per line across nine paylines, the theoretical bet spread runs from roughly $0.09 on the low end (one coin per line at $0.01) up to the listed max bet of $45 (five coins per line at $1). The official RTP can vary by operator, so check the game info in your casino lobby to see the exact percentage offered where you play. Volatility isn’t printed in the specs here, but the combination of modest max bet and feature-driven payouts suggests a game that leans toward medium volatility: you’ll see regular small wins and the chance for bigger payouts when bonus rounds hit.
Bonus rounds and special features that lift the reels
The game packs two distinct bonus experiences. The "Destination bonus game" is a pick-and-click style feature that sends you to different planetary stops with prizes behind each location — think choices that reveal cash amounts, multipliers, or free spins. The "Beam 'em Up bonus game" ramps up the sci-fi fun with a sequence that can stack rewards or award progressive multipliers as symbols are 'beamed' into place. Scatter symbols — Rocket, Saucer, and Shuttle — are tied to bonus activation, and bonus rounds are the main route to the largest payouts here. These features are designed to break up standard spins and offer moments where a patient player can score a meaningful payday without complex mechanics.
Smart play tips you can use right away
Treat this title like any feature-led slot: start with the demo to learn how often bonus rounds trigger, then size your real-money bets based on what you see. If you want longer play, use smaller coin sizes and fewer coins per line to keep spins affordable while still qualifying for features. If a bonus hits, consider modest bet increases only if your bankroll can handle losses afterward — chasing bigger wins rarely pays off. Set session limits, divide your bankroll into chunks, and walk away after hitting a preset win or loss threshold. Those simple rules help you enjoy the game without surprises.
Final word: ready to give it a spin?
If you like bright, theme-forward slots with straightforward paylines and memorable bonus rounds, this game is worth a test spin in demo or low-stakes mode. The design keeps things light while the bonus games offer moments of real excitement, especially when scatters line up.
