Core Gameplay Overview

• Grid and pays: 5x5 layout with 19 win lines, featuring 5 Low symbols and 4 High symbols.
• The Jumpasaurs: Up to three Jumpasaurs stand under the reels in the base game. Any Mystery Symbol landing on an active reel gets collected by the Jumpasaur below it.
• Mystery reveals: Collected Mystery Symbols can reveal Coins, Wild Multipliers, or a Scatter.
• One-scatter bonus entry: Revealing a single Scatter launches Extinction Spins with 8 spins.

Mystery Symbols: Coins, Wild Multipliers, and Scatters

When a Mystery Symbol lands on a reel that has a Jumpasaur active:

• Coins: Reveal up to 10 coin prizes, each coin showing values like 1x, 2x, 3x, 5x, 8x, 10x, 15x, 20x, 25x, 50x, or 100x.
• Wild Multipliers: Wilds can appear with multipliers of 2x, 3x, 5x, 8x, 10x, 15x, or 20x, boosting any line wins they are part of.
• Scatter: A single revealed Scatter triggers the Extinction Spins feature.

This collection mechanic makes every Mystery Symbol feel meaningful, especially when multiple active reels and Jumpasaurs are in play.

Extinction Spins Free Spins Bonus

• Entry: Reveal one Scatter from a Mystery Symbol to get 8 spins.
• All reels active: All five Jumpasaurs move into position and stay for the full bonus, so every Mystery Symbol on any reel is collected.
