Mad Clones by Bubi Studios Slot Overview

Mad Clones by Bubi Studios brings cartoon creatures, glowing chemicals and slime-covered machinery into a neon laboratory. Its Wild multipliers provide a mechanical connection to The Dog House, but here, filling a capsule with matching creatures transforms other creature symbols across the grid.

The Clone Capsule combines creature transformations with Voltage multipliers, while free spins expand the grid and introduce a persistent Mutagen Tank multiplier. High volatility accompanies a maximum win of 25,000x the bet. Explore the experiments yourself with the free demo on BonusTiime, without an account or deposit.

Volatility

High volatility means fewer hits and larger swings, so online slot gameplay can feel uneven and more demanding.

Mad Clones Slot Features

Intro screen of Mad Clones

Mad Clones combines Clone Capsule, Voltage, Bonus Tubes, Lab Accident, Mutation, Clone Army, Double Dose, Overdose, Live Wire, Perfect Copy, and Random Sample into one experimental setup.

Clone Capsule

The Clone Capsule sits on reel 3 in the base game, or reels 3 and 4 during free spins. When one creature fills the capsule, every other creature on the grid clones into it. If both capsules fill in free spins, the left capsule copies the grid.

Voltage

Voltage activates whenever a capsule fills. The dial stops on x1, x2, x3, x5, x8, x12, x20, x30, x60 or x120. In the base game, each Wild inside a full capsule adds its own value before the dial multiplies the spin’s wins.

Bonus Tubes

Bonus Tubes land only in the base game, with at most 1 per reel. They choose the lab by count and shape the feature start. Three Tubes open Lab Accident, four trigger Mutation, and five unlock Clone Army, the hidden 10-spin lab.

  • Lab Accident: 8 free spins, Mutagen Tank from x1.
  • Mutation: 9 free spins, locked capsules, Mutagen Tank from x3.
  • Clone Army: 10 free spins, locked capsules, Mutagen Tank from x6.

Lab Accident

Lab Accident starts with 3 Bonus Tubes and awards 8 free spins on the big lab grid. The Mutagen Tank never resets, so each cloning event and every Wild feed into it. The feature keeps the action focused on steady accumulation rather than retriggers.

Mutation

Mutation starts with 4 Bonus Tubes and gives 9 free spins. It adds locked capsules, so a creature that fills a capsule stays there for the rest of the feature. The Mutagen Tank starts from x3, which gives the bonus stronger built-in momentum.

Clone Army

Clone Army is a hidden free-spin state that starts with 5 Bonus Tubes in the base game. It plays like Mutation but awards 10 free spins and begins the Mutagen Tank from x6. The feature is not directly selectable in the menu.

Bonus Buy

This feature lets you buy feature starts or boost activation chances directly.

  • Double Dose: x2 the bet per spin; more Bonus Tubes land.
  • Overdose: x5 the bet per spin; Bonus Tubes appear far more often.
  • Live Wire: x75 the bet per spin; capsule starts full every spin.
  • Lab Accident: x100 the bet; 8 free spins on the big lab grid, with the Mutagen Tank from x1.
  • Mutation: x250 the bet; 9 free spins, filled capsules stay locked and the Mutagen Tank starts at x3.
  • Random Sample: x500 the bet; 40% Lab Accident, 48% Mutation, 12% Clone Army worth at least 1,000x.
  • Perfect Copy: x1,000 the bet; filling all 15 cells awards 25,000x, with a stated chance of 3.86%.

Mad Clones Slot Review

Mad Clones builds its identity around a mad laboratory full of cloned creatures, glowing tubes and a capsule that spreads symbols across the grid. The neon sci-fi look fits the mechanics neatly, while the laboratory background and mutant artwork give the slot a clear visual hook without relying on clutter.

The Clone Capsule gives Mad Clones its best twist, because matching creatures can spread through the grid and then feed into Voltage and the Mutagen Tank. That creates real variety, but the high volatility and expensive buy options keep the action firmly in swing-heavy territory rather than steady base-game play.

Mad Clones offers seven paid options, from Double Dose at x2 the bet per spin up to Perfect Copy at x1,000 the bet, but buying features does not improve the stated RTP. The 25,000x ceiling gives the design a proper target, and the cloning system stops it from feeling like a routine 243-ways release, even if the structure is still built around big swings.

Mad Clones Slot FAQ

How Does The Bonus Trigger In Mad Clones?

Mad Clones opens its bonus through Bonus Tubes in the base game. Three Tubes trigger Lab Accident with 8 free spins, four trigger Mutation with 9 free spins, and five trigger Clone Army, the hidden version with 10 free spins. Bonus Tubes do not land during the lab.

What Do The Buy Options Cost And Give?

The menu holds three features that stay on and four one-round buys. Double Dose costs x2 the bet per spin, Overdose x5 the bet per spin and Live Wire x75 the bet per spin. Lab Accident costs x100 the bet, Mutation x250 the bet, Random Sample x500 the bet and Perfect Copy x1,000 the bet. Random Sample draws 40% Lab Accident, 48% Mutation and 12% Clone Army, while Perfect Copy offers a 3.86% chance of filling all 15 cells for 25,000x.

What Is The Max Win In Mad Clones?

The max win is 25,000x the bet. The rules state that the round ends at once when this limit hits, and any remaining free spins get forfeited. That cap applies across the game modes listed in the rules, including the base game and the buy options.

Is There A Free Demo For Mad Clones?

Yes, the free demo is playable on this BonusTiime page without a deposit or account. That lets you test the grid, the Clone Capsule, and the bonus menu before playing with real funds. The game is exclusive to Stake in its real money form.

How Does The Clone Capsule Mechanic Work?

The Clone Capsule sits on reel 3 in the base game and on reels 3 and 4 in free spins. When one creature fills a capsule, the other creatures on the grid clone into it. Mutagen Wilds only land there and can carry x2, x3, x5, or x8.
