Play Anderthals Online

Anderthals free play is available right here on Slottomat — no download, no registration required. Just For The Win released this prehistoric slot in April 2020, and it's still one of the studio's most distinctive titles.

Quick take: A high-volatility game with a unique Feature Spots system that makes the base game genuinely interesting. Best for players who can handle dry spells and have a bankroll to match.

Anderthals Slot Overview

Anderthals drops you into a Stone Age world of volcanic backdrops, sabre-toothed tigers, and a lovable caveman hero named Andy. The 5-reel, 4-row grid runs 40 fixed paylines and features the studio's signature Feature Spots mechanic — a row of five modifier spaces that sits above the reels and fires effects whenever a burning torch symbol lands below.

The RTP is 96.12%, a nudge above the 96% industry average. Volatility is high, and the hit frequency sits at 20.24%, so about one in five spins returns something. That makes sessions feel active even during quieter stretches. Bet range is £0.10 to £100 per spin.

Game Features and Mechanics

The Feature Spots are what set Anderthals apart. Above each of the five reels sits a Feature Spot space. When a Feature Symbol — the burning torch icon — lands on a reel, it activates the Feature Spot above it. Each active spot delivers one of these effects:

• Expanding Wild — stretches to cover the full reel
• Extra Wilds — additional wild symbols are placed on the grid
• Wild Multipliers — a 2x or 3x multiplier attaches to wild symbols on that reel
• Re-spin — a respin fires with expanding wilds and multipliers already locked in

The T-Rex wild symbol substitutes for all regular symbols. It's also the highest-paying icon in the game at 32x for five of a kind on a payline. Wins pay left to right across all 40 lines on every spin.

When multiplier wilds land together on a winning line, the values combine multiplicatively. A 2x and a 3x wild on the same line produce a 6x total — not 5x. That exponential math is what makes the Feature Spots mechanic capable of producing large base-game hits even before the free spins round.

Free Spins Bonus

The free spins round triggers through the Feature Spots system: when a Feature Symbol lands on a reel with the Free Spins Feature Spot active above it, the bonus opens. You begin with 8 free spins. Each additional Feature Symbol and Free Spins Spot combination adds 2 more spins, which is the retrigger mechanic — there's no hard cap, so rounds can extend well beyond the starting count.

During free spins, all previously active Feature Spot modifiers stay in place for the entire bonus. That persistence is the key: expanding wilds and multiplier wilds continue to fire throughout, rather than appearing randomly. One free spin with two multiplier wilds on a winning line alone can deliver a hit worth a significant multiple of your bet. The game's 2,219x maximum win is primarily built on these stacked modifier scenarios during the bonus.

RTP, Volatility & Payout Potential

At 96.12% RTP, Anderthals is designed to return about £96.12 per £100 wagered over a very long run. That's above average, and it shows Just For The Win didn't cut corners on player returns.

High volatility means you trade win frequency for win size. Stretches of 50–100 spins without a major return are normal. When the game pays, particularly during the bonus with stacked modifiers, it tends to pay significantly.

That ceiling is exciting but not unrealistically remote. Most sessions won't reach it, but the Feature Spots system creates genuine moments where large multiplied wins stack up.

Practical bankroll advice: bring at least 150–200x your chosen bet per session. At £0.50/spin that's £75–£100. At £2/spin, budget £300–£400. Short sessions often end before the modifier system has enough time to deliver its best hits. For more on managing these swings, our high payout slots guide has useful context.

Is Anderthals Worth Playing?

Anderthals is a well-executed high-volatility slot with real mechanical depth. The Feature Spots system means the base game has structure beyond just waiting for a bonus round. Torch symbols landing in the base game can trigger re-spins and multiplier wilds on their own, which keeps sessions engaging between free spin rounds.

What works well: 96.12% RTP is genuinely above average.The Feature Spots modifier logic is distinctive and rewards understanding the system. Bet range accommodates cautious and aggressive players alike.

What to watch out for: High volatility demands patience and a deep enough session budget. During quiet stretches, the base game can feel slow. The prehistoric caveman theme is charming but niche — if the setting doesn't appeal, other mechanics-forward titles might serve you better.

Verdict: 8/10. Anderthals does exactly what it sets out to do — a fair, feature-rich, high-volatility game with serious payout potential. The Feature Spots system separates it from most games in its category. If you're built for the ride, it's an excellent choice.
