Norway, Oslo - November 13, 2026 - Step into the shoes (claws?) of the Math Mouse and use creative arithmetic to combine dice rolls and cards on a quest to defeat the Necrodicer’s army of corrupted numbers in Talystro! The independent Norwegian studio Filiokus has released a second demo for its deck-building roguelite.
Talystro isn’t just about stacking abilities and building synergies to deal 9999+ points of damage, though. Taking down the corrupted army of the Necrodicer will require the heroic Math Mouse to unleash each enemy's exact number- too low, or too high, and you won’t even leave a scratch! Each card in the player's hand contains unfinished calculations which must be completed by using the rolled dice each turn.
The second demo brings with it a new act, The Haunted Crossing, leading to the infamous 67 Dreadhorse boss fight! That’s not all, though; look forward to a brand new level progression system, more cards, artefacts, and enchantments to experiment with, previously unseen corrupted numbers in the Necrodicer’s ranks, and a new scoring system complete with leaderboards for the high-score chasers out there!
Developer Filiokus's signature hand-drawn animation style has continued to develop since the first demo. Fresh detail has been woven into the visual style, and Talystro’s fluid animations have continued to grow, ensuring every corrupted number has a personality all of its own! This is complemented by Talystro’s music and sound effects, which have continued to evolve, adding additional ear-wormy charm.
“Math is strategic, creative and rewarding, and so is Talystro!” said Martin Lothe Sæterdal, CEO at Filiokus. He added: “It combines logic, strategy, and aritmethics with monster hunting, battleaxes, and fireballs, what’s not to like? Number crunching has never been so literal or vicious!”
Key Features:
- Arm yourself with arithmetic by using dice and card combat to deal precise damage and defeat enemies!
- Play as the Math Mouse and defeat the corrupted number army of the Necrodicer.
- 52 cards, 19 artefacts, and 12 enchantments await! Build a deck with one route to success, or keep it flexible, who are we to tell you what to do?
- Unlockable abilities carry over between runs, changing the way you play as you progress.
- Hand-drawn retro-cartoon animations, atmospheric music and satisfying sound design throughout the adventure
- The second demo offers The Haunted Crossing act, a new boss fight, an expanded pool of cards, enchantments and artefacts, and much more!
The second Talystro demo is now available for free on Steam for PC and Mac, and the game is set to launch in early 2027, with a full playtest set for later this year. Players excited to decimate the Necrodicer’s forces can go to Steam now to download the demo and register for the playtest!
