Press release:
November 4, 2026 | Chugga Games is excited to announce that Slumber Realm, the dice roguelike where you battle your childhood fears in your dreams, launches today on Steam at 10am PT / 1pm ET / 6pm GMT / 7pm CET. The game is led by Brian Cronin, whose previous work includes Monster Train, Inkbound, and Natural Selection 2. It launches at $11.99 / £10.75 / €12.25, with 10% off for the first 10 days.

Launch is only the start. Every Wednesday for the next four weeks, Slumber Realm gets a free mini-expansion, added automatically for everyone who owns the game. Each one is a themed mixtape of new Cards and other surprises, starting with the night-themed Midnight Mix on November 11. The other three will be revealed week by week.

The demo remains available on Steam for anyone who’d like a quick nap before committing to the full night’s sleep.

Slumber Realm was named one of the dice games to watch in 2026 by The Escapist, which called it “one of the best roguelite demos currently available on Steam”, and was previously showcased at GDC 2026 and Tiny Teams 2025.

About The Game
In Slumber Realm, your childhood fears follow you into your dreams, and they’re not going down without a fight. It’s a ’90s-soaked dice roguelike where drafting the right Cards into your backpack and rolling the die can chain your whole build into one explosive turn.

Wake up! Here’s how to play in 4 easy steps

Draft: Add a Card to your backpack
Roll: Toss the die and see what lands
Trigger: Cards trigger if the die lands in their range
Activate: Cards activate in sequence!

That’s a whole turn. Grab your trusty d6, arrange your backpack so one lucky roll sets everything off, and see how far it goes in snappy 30-minute runs.

BUT WAIT… There’s more!

COMBOS! COMBOS! COMBOS!
Craft new degenerate combos to break the game, over and over and over again.

Over 150 Cards, including a Rusty Nail and a Sock Full of Nickels
Over 40 Memories to make battles easier… or weirder
Over 35 tasty Snacks to boost your runs

MIX & MATCH CLASSES
Pick any two Aspects (our word for classes) and draft Cards from both. For example:

Tactical + Sk8er: stack Vulnerability on the enemy, then use Tricks to trigger your Cards again and again.
Gamer + Tinker: stack the odds with extra dice while you upgrade your Cards.

Every pair mixes a different set of Cards into your backpack, so no two runs build the same machine.

FIGHT YOUR KNIGHTMARES
Fall asleep and the school day follows you in.

The Lunch Lady is serving seconds whether you want them or not.
Your Geology Homework is still due.
The Werecoach will make you run laps until you howl.
The Alarm Clock is furious that you’re still in bed.
Plus plenty more Knightmares to discover and unlock as you play.

GO TO YOUR ROOM
Spend your Allowance on nostalgic ’90s memorabilia:

Retro video games
Lava lamps
Boomboxes
Inflatable chairs
Sick skateboards
Everything you need to survive Y2K.

Every morning your decorations earn Cool Points to spend on the Corkboard, so every time you wake up there is something new to unlock:

Cards
Memories
Snacks
Aspects
New Knightmares
Other surprises

TL;DR This one’s perfect for fans of Dicey Dungeons, Slay the Spire, and Monster Train.
