Roguelike dice-and-card deckbuilder Talystro gets second demo

Norwegian indie studio Filiokus has released a second free demo for its math-driven roguelite deckbuilder Talystro on Steam. The build adds The Haunted Crossing act, a new boss, and a larger card pool ahead of the full launch in 2027.

Norwegian indie studio Filiokus has released a second playable demo for Talystro, its math-driven roguelite dice-and-card deckbuilder, on Steam. Announced on November 13, 2026, the free build follows the first public demo from April 29, which holds a 95 percent positive rating from 23 user reviews at the time of writing. Gamirror Games is listed alongside Filiokus as the publisher on the Steam page.

Talystro casts players as the Math Mouse, who takes on the Necrodicer and her army of corrupted numbers. Where deckbuilders such as Slay the Spire have players wear down a health bar, enemies here are living numbers that are destroyed only when an attack matches their exact value.

Exact-value combat and The Haunted Crossing

Each turn, players roll dice and slot them into cards that hold unfinished calculations, along with variables, modifiers, and spell effects. The order in which cards and dice are played decides whether the final result lands on the target number. Between fights, a Crossroads screen lets players pick their route through the run.

The second demo adds a new act, The Haunted Crossing, which ends in a boss fight against the 67 Dreadhorse. According to Filiokus, the build includes 52 cards, 19 artifacts, and 12 enchantments, plus corrupted numbers not seen in the first demo. It also introduces a level progression system, a scoring system with leaderboards, and unlockable abilities that carry over between runs. The studio says its hand-drawn animation has been developed further since April.

“Math is strategic, creative, and rewarding, and so is Talystro,” said Martin Lothe Sæterdal, CEO of Filiokus.

Low system requirements on Windows, macOS, and Linux

The demo is free to download on Steam, where it is listed for Windows, macOS, and SteamOS/Linux. Minimum requirements are modest: a 1.7 GHz processor, 1 GB of RAM, and Intel HD Graphics 3000 on Windows, with 2 GB of storage. The macOS version needs macOS 10.13 and a Metal-capable GPU on Intel or Apple Silicon, while the Linux version asks for 64-bit Ubuntu 12.04 or newer. Both need 600 MB of storage.

Filiokus says the full game will launch in early 2027, and the Steam listing currently shows Q2 2027. It will feature three acts. A full playtest is planned for later this year, and registration is open on the Steam page.
