Graphics and audio

The review describes impressive, carefully designed graphics across the mobile and desktop versions. HD scenery fills the background, with ships and fog moving through a picturesque mythical setting suited to the two warriors represented by the Mythos video slot game. The reel symbols and triggered features also use striking animated effects.
The theme tune is presented as a melody reflecting the era suggested by the setting, while winning symbol combinations produce a high-pitched sound.
HOW TO PLAY THE MYTHOS SLOT GAME

Popiplay often varies its reel grid across online slots to create a distinctive layout. Mythos uses a 5x4 reel arrangement with 20 paylines.
There are 11 regular-paying symbols, with combinations of 3, 4, or 5 paying when aligned. The stacked snake symbol pays for 2, 3, 4, or 5 symbols landing from left to right across a payline.
Mythos uses Hercules holding a spear as its wild symbol. He substitutes for each of the regular symbols.
The Heroic Frame feature in the base game can create more combination wins by turning symbols into wilds and adding multipliers. It is available while spinning for the free spins bonus, where the review identifies the potential for the slot’s largest wins.
Reported payouts for regular-symbol 5-symbol combinations are:
- Staked Snake: 10x
- 2 Headed Red Wold: 3.75x
- Pegasus: 3.75x
- Minotaur: 3x
- Medussa: 3x
- Whimsical Creature: 3x
- Green Cyclops Man: 3x
- Greek Symbols: 1.5x

BONUSES AND FREE SPINS

The original review highlights that Mythos includes engaging features in the base game, rather than requiring players to wait for a bonus before pursuing larger wins. The two sections below outline when its different features can appear.
BASE GAME FEATURES
- Heroic Frame: This base-game feature activates when a Hero symbol lands on the reels. It frames that reel position and remains sticky for 10 spins before changing into a Wild symbol.
- Extra Multiplier: When a Hero symbol lands in a cell containing a Heroic Frame, the spin’s multiplier rises by 1. The Extra Multiplier applies to every winning combination and returns to 1x when a fresh 10-spin cycle starts.
FREE SPINS BONUS AND FEATURES
- Free Spins: Landing the Zeus Thunderbolt scatter on reels 1, 3, and 5 triggers 10 free spins.
- Free Spins Sticky Wilds: During the free spins bonus, a wild remains sticky when it lands on the reels. The original review reports that, as several sticky wilds accumulated near the end, almost every spin became a ‘Big Win.’
BONUS BUY FEATURES
- Random Wilds: This feature requires a bet between 0.20 and 20.00. It costs 50x the stake and awards free spins containing a random number of wilds.
- 2x2 Wilds: This feature can be purchased with a spin bet between 0.20 and 7.00. The price is 120x the stake, awarding free spins with 4 sticky wilds on the reels.
- 3x3 Wilds: The feature is available for a spin bet of 0.20 to a maximum of 2.00. It awards 10 free spins with a minimum of 6 sticky wilds, at a cost of 400x the spin bet.
TECHNICAL DETAILS
The original review lists Mythos with an RTP of 95.48% and high-variance gameplay. Its stated maximum win is 2,800x the bet, with a min-max betting range of 0.20 to 50.00 per spin.
EVAN CARRINGTON’S GCCans OPINION OF MYTHOS

Popiplay has created an appealing theme that may attract slot players, although the RTP could discourage some of them. It argues that the provider took an unnecessary risk by pairing the theme and familiar features with a lower RTP.
For players who are not concerned about losing half a percent, the review considers Mythos worth trying. Its base-game features provide opportunities for wins, but players seeking wins significant enough to affect their bankroll would need to enter the free spins bonus.
