Rules and Gameplay

Crazy Lab is a video slot game developed by FunTa Gaming that introduces an innovative cascading reels feature. Players can start by selecting their bet, ranging from $1 to $500, using intuitive controls that resemble test tubes. The game is played across a layout of 4-4-3-4-4 with 768 ways to win, providing ample opportunities for winning combinations. Once the bet is set, pressing the spin button initiates the game, and winning symbols are replaced by new ones, potentially creating additional wins in a single spin. This mechanic adds a dynamic layer to the gameplay, making each spin unpredictable and exciting.

Bonus Features

Crazy Lab offers several unique bonus features that enhance the gaming experience:

  • Bio Lab Bonus Game: Triggered by landing DNA strand bonus symbols on reels 2, 3, and 4. This feature allows players to progress through different levels with each win, increasing potential payouts with multipliers.
  • Cascading Reels: This feature allows for multiple wins on a single spin, as winning symbols disappear and new ones fall into place.
  • Autoplay Feature: Players can choose to initiate up to 50 autospins, adding convenience and continuous play without manual intervention.

These features not only provide opportunities for significant wins but also make each session with Crazy Lab thrilling and full of surprises.


The symbols in Crazy Lab are creatively designed to fit the scientific theme of the game:

  • Mad Scientist: Top paying symbol.
  • Assistant: High-value symbol.
  • Lab Rat: Mid-value symbol.
  • Microscope and Goggles: Lower-value symbols.
  • Red and Green Potions: Lowest-value symbols.

Each symbol contributes to the game’s narrative, enhancing the player’s immersion into the world of a quirky scientist’s laboratory.


Symbol Payout for 5x
Mad Scientist x0.64
Assistant x0.56
Lab Rat x0.48
Microscope x0.40
Goggles x0.32


Crazy Lab boasts a non-traditional approach to paylines with its 768 ways to win, where wins are awarded for any left-to-right combination of matching symbols on adjacent reels. This setup not only simplifies the gaming experience but also increases the chances of winning, making each spin an exciting prospect.

Pros & Cons

Pros Cons
768 ways to win, enhancing chances of payouts. High minimum bet of $1 might deter low-stake players.
Unique cascading reels feature for continuous wins. Medium volatility may not suit those looking for more frequent, smaller wins.
Innovative Bio Lab bonus feature with multipliers. Limited availability as the game is not very popular.

Minimum and Maximum Bet

Crazy Lab offers players a wide range of betting options, starting with a minimum bet of $1, which is higher than many other slots, making it less accessible to those on a smaller budget. On the other hand, the maximum bet can go up to $500, catering well to high rollers who seek the thrill of betting large amounts on each spin.

Game Jackpot

The game features a staggering maximum win potential of up to 750,000x the player’s stake. The Return to Player (RTP) rate is set at 95.15%, which is slightly below the industry average but typical for games with high maximum payouts. The game’s variance is medium, meaning that players can expect a balance between the frequency of wins and the payout amounts, suitable for players who enjoy moderate risk.
