· the mutant rat card battler for PC

Steal their rats. Mutate yours. Blame Igor.

A card battler for PC where one clever move turns the whole board. Five rats, nine squares, and a rival who thinks they've already won. You'll learn it in one duel. You'll want a rematch before it ends.

It's free: just join the lab on Discord. No card, no password.

▼

Every rat is a card. Every card has teeth.

Put a rat next to a rival's. If your number beats theirs, that rat changes sides. Simple, until they do the same to you with their last card. When the board is full, whoever holds more rats wins, and you'll know exactly which move cost you the duel.

A turn-based card duel against Harry Botter on the three-by-three board

Place, flip, steal

Five rats each, nine squares, one board. Nothing is safe until the last card lands.

Three elements

Mutant beats Radioactive, Radioactive beats Mechanical, Mechanical beats Mutant. The weaker rat loses a point on every side before the numbers are compared.

The four dirty tricks: Super Cheese, Rat Trap, Taser and Fog

Dirty tricks

Super Cheese makes one of your rats stronger, a Rat Trap waits on an empty square, the Taser freezes a rival rat, and Fog hides your numbers. One per turn. Pick the moment that hurts most.

Evolve something dangerous

Level a rat up, roll it into the evolution chamber and wait. What comes out has new art, new numbers and new problems. Snifire dreams of being a dragon. Give it time.

Meet the rats

They blink, gloat, sulk and attack, and you will end up with a favourite. The full game has 177 to collect. A few residents of Floor 1:

Ratus, a neutral rat from Laboratz

Ratus

The basic rat, found behind some furniture and caught with a piece of cheese.

Snot, a neutral rat from Laboratz

Terribly ferocious, with insane strength. Breathes fire. From both ends.

Walk in as you

Before the first duel, build the student who walks into the lab: build, face, hair, outfit and accessories, drawn in the same style as the rats. That's your face on the line from now on. Igor will still get your name wrong.

Questions from the lab

What is Laboratz?

Laboratz is a tactical card battler for Windows PC. You collect mutant rats, place them on a three-by-three board and capture your rivals' rats by beating their numbers and elements. Between duels you level your rats up and evolve them in the lab.

Is Laboratz free?

The Closed Beta is free: your code costs nothing and we never ask for a card. The price of the full game hasn't been announced.

How do I join the Closed Beta?

Download the Laboratz Launcher from this site; anyone can install it. Then get your free Beta code: join the lab on Discord, open #get-beta-access, and enter the code in the launcher.

How long does my Beta code last?

One code per Discord account, good on 2 PCs for 30 days. The lab gives out a limited number of codes each day: if today's are gone, come back tomorrow.

What do I need to play?

A PC with Windows 10 or 11 (64-bit), an internet connection and about 1 GB of free space. On a PC with Smart App Control turned on, the Beta can't run yet.

How do the card duels work?

Each rat card has a number on its four sides. Place a rat next to a rival's rat: if your facing side is higher, the rival's rat becomes yours. Elements (Mutant, Radioactive, Mechanical) and dirty tricks change the maths. When the board is full, whoever holds more rats wins.

How many rats are there?

The full game has 177 rats to collect, neutral or of one of the three elements, and many of them evolve into new forms. The Closed Beta includes the rats of Floor 1 and the fire dragon line from Snifire to Rapalm.

Is it like Triple Triad?

It's the same family: a three-by-three board, numbers on four sides and cards that flip. Laboratz adds elements, dirty tricks and rats that evolve into something else.

Is this the Laboratz from Facebook?

Yes. Laboratz began as a Facebook game in 2013. This is the same lab rebuilt for PC: everything redrawn, with new rivals.

Is there online multiplayer?

Online duels against other players are in development, on dedicated servers that decide every result. They are not part of the Closed Beta.

When does Laboratz come out, and on which platforms?

Laboratz is in development for Windows PC, and its Steam page is coming soon. No release date has been announced.

Which languages does Laboratz support?

The game's interface is in English, Spanish and Arabic.
