Professor Kaboom Slot Demo by Pevrux

Professor Kaboom by Pevrux Slot Overview

Professor Kaboom by Pevrux fills a spooky laboratory with copper pipes and glowing green machinery. It shares Pay Anywhere wins with Waylanders Forge, but here explosions stamp multiplier tags onto grid cells, making the laboratory more than a colourful backdrop.

During free spins, destroyed cells build Reactor Heat, unlocking repeated board-clearing meltdowns once the gauge fills. High volatility and a maximum win of 10,000x the bet add weight to this inventive experiment. Explore the reactions yourself with the free demo on BonusTiime, without an account or deposit.

Professor Kaboom Slot Specifications

Professor Kaboom uses a 5×5 grid and Pay Anywhere wins: any symbol counted 7 or more times anywhere on the grid pays, and the copies do not need to touch or line up, with higher values at 8-9 and 10+ copies. Winning symbols fizz away, the rest slide down, fresh ones drop in, and the board is checked again until no new win forms. The house edge is 3.80%, which keeps the long-term return tightly defined in this Pevrux slot.

RTP (Return to Player)

Volatility

High volatility means Professor Kaboom can swing sharply, with longer quiet spells before stronger hits land.

Max Win

10,000x the bet caps the game; a €1 spin tops out at €10,000.

Professor Kaboom Slot Features

Professor Kaboom packs in Pay Anywhere wins, Bolt Wild, Lab Tricks, Boom Tags, and the three free-spin labs: Bubble Trouble, Tesla Storm, and Big Kaboom.

Bolt Wild

Bolt acts as the wild symbol. He counts as every winning symbol at the same time, so one Bolt can complete two different matches on the same board. He has no value of his own and disappears with the symbols he helps. A tag on his cell counts for every match he joins.

Lab Tricks

Lab Tricks trigger at the pause, when a chain of drops ends with no new win. Potion Bombs go first and blast a 3×3 square, including their own cell. Tesla Coils fire next from left to right, hitting their own cell and 4 more cells.

Potion Bombs can land in every mode. Tesla Coils only appear in Tesla Storm and Big Kaboom. Blasts remove symbols, Bolts, and other Potion Bombs, but they never remove a Reactor, another Tesla Coil, or a tag. Fresh symbols then drop and the checking starts again, so a round ends only once no win forms and no trick is left.

Boom Tags

Every cell a blast hits keeps a multiplier tag. Tags stick to the grid position, so any later symbol landing there uses it. A Potion Bomb prints one value from 2x to 25x onto each cell in its square, and a square at the edge of the grid is smaller. A Tesla Coil rolls 3x to 25x for each of its 5 hit cells.

Tags on the same cell add together. A winning symbol starts from its table value, then the summed tags scale that win. In the base game and in Bubble Trouble, tags clear when the round ends. In Tesla Storm and Big Kaboom, they stay until the last free spin.

Reactors & Free Spins

The Reactor starts the free spins feature. Landing 3 Reactors starts Bubble Trouble, 4 starts Tesla Storm, and 5 starts Big Kaboom. Each mode gives 8 free spins, and landing 3+ Reactors while the feature runs adds 5 more spins.

Reactor Heat & Lab Meltdown

The Reactor Heat gauge works only in free spins. Every destroyed cell heats it one step, whether a winning symbol, a Potion Bomb, or a Tesla Coil causes the hit. When the gauge fills, Lab Meltdown destroys all 25 cells and adds one value from 2x to 25x to every cell tag.

Those tags stay until the feature ends. If the gauge is already full, it stays full, so each remaining free spin ends with another Lab Meltdown. Bubble Trouble starts empty, Tesla Storm starts a quarter hot, and Big Kaboom starts half hot.

The Three Labs

Each free-spin lab changes the starting heat and the available tricks. Bubble Trouble gives 8 free spins with only Potion Bombs. Tesla Storm gives 8 free spins, starts a quarter hot, and adds Tesla Coils. Big Kaboom gives 8 free spins, starts half hot for the most Lab Meltdowns, and runs Tesla Coils with lasting tags.

Mystery Potion randomly picks one of the three labs, or gives a single regular spin instead. The published chances are 38.92% for Big Kaboom, 32.78% for Tesla Storm, 19.13% for Bubble Trouble, and 9.17% for a single regular spin.

Game Modes

The bonus menu sells six modes: two spin modes that stay on every round until you switch them off, and four feature modes bought for a single round. Reactor Boost plays at 1.5x the bet per round and makes Reactors land more often. Overcharge plays at 3x the bet per round and makes Reactors land far more often.

Bubble Trouble costs 100x the bet for 8 free spins with the gauge cold, Tesla Storm 300x the bet for 8 free spins a quarter hot with Tesla Coils, and Big Kaboom 1,000x the bet for 8 free spins half hot; all three start their free spins straight away. Mystery Potion costs 500x the bet and picks one of the three labs, or gives a single regular spin instead. Every mode keeps the same 96.20% RTP and the same 10,000x cap.

Professor Kaboom Slot Review

Professor Kaboom uses a dark laboratory setting with green machinery, copper pipework and a comic mad scientist look that matches its reactor theme. The identity comes from the board itself, where bursts, tags and heat levels shape the action instead of mere background decoration. The result feels sharp and unusual.

The best part is the way Pay Anywhere wins feed into Boom Tags and the Reactor Heat gauge. Every destroyed cell matters, because it can power up later wins through tags or push the board towards Lab Meltdown. High volatility makes those systems feel meaningful rather than cosmetic.

Professor Kaboom can extend its free-spin features with extra Reactors, while a full Reactor Heat gauge triggers repeated board clears. That gives the game real staying power, especially with 10,000x the bet on the table, but the high variance keeps it demanding rather than forgiving. Distinctive and tense.
