Winning symbols cascade away and charge the Quantumeter, while Double Helix scatters lead to the free spins.
Game mechanics
The 6-reel, 4-row grid starts at 4,096 ways to win and can expand up to 262,144 ways through the Dynamic Payways system: x2 multiplier symbols above the reels double the payways on their reels and multiply together for up to a x64 boost.
Reels cascade, so winning symbols are removed and new ones drop in, letting one spin chain several wins. Every cascade fills the Quantumeter, and a full charge triggers one of three random modifiers.
Features
- Quantum Wild. The game's highest-value symbol, substituting for regular symbols to help complete winning ways.
- Cascading Reels. Winning symbols are removed from the grid and new symbols fall in to fill the gaps, repeating for as long as new wins keep forming.
- Quantumeter. A meter that fills with each cascade. When fully charged it fires one of three random modifiers: Quantum Wilds (adds 2-6 wilds), Metamorphosis (converts 5-8 symbols into one random type) or Disintegration (removes the low-value aliens and adds 2 wilds).
- Free Spins Bonus. Landing 3 to 6 Double Helix scatters awards 10 to 25 free spins, during which the Quantumeter starts pre-charged by 1-2 levels per spin.
- Dynamic Payways x2 Multipliers. Multiplier symbols above the reels double the payways on the reels involved and multiply together, boosting the ways to win by up to x64 for a maximum of 262,144 ways.
Why Dr. Toonz has five RTP settings
Play'n GO's own game data for Dr. Toonz lists five RTP versions: 84.25%, 87.25%, 91.25%, 94.25% and 96.25%. Each version keeps the name and artwork, with the maths tuned to a different long-run return. The casino picks which one it runs, within any minimum its regulator sets. Studios say they offer several because markets differ: minimums vary between regulators, and casinos weigh taxes, margins and commercial terms. A higher setting does not guarantee a profit, and a short session can finish up or down either way. This demo uses virtual credits: nothing is deposited, withdrawn or paid out, so the setting has no financial effect.
