Talystro Gets a Second Free Demo, Adding a New Act and Boss Before 2027 Launch

Talystro second demo, Digi Mart USA News: Norwegian indie studio Filiokus has released a second free playable demo for Talystro, its math-driven roguelite dice-and-card deckbuilder, on Steam. The announcement was made on November 13, 2026, and follows the first public demo released on 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. The game casts players as the Math Mouse, who battles the Necrodicer and her army of corrupted numbers.

Unlike deckbuilders such as Slay the Spire, where players wear down a health bar, enemies in Talystro are living numbers that are destroyed only when an attack matches their exact value.

Each turn, players roll dice and place them into cards that hold unfinished calculations, along with variables, modifiers and spell effects. The order in which cards and dice are played determines whether the final result lands on the target number.

Between fights, a Crossroads screen lets players choose 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, along with 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.

Martin Lothe Sæterdal, CEO of Filiokus, said: “Math is strategic, creative, and rewarding, and so is Talystro.” The demo is free to download on Steam for Windows, macOS and SteamOS/Linux. Filiokus says the full game will launch in early 2027, while the Steam listing currently shows Q2 2027. The full game will feature three acts, and a full playtest is planned for later this year, with registration open on the Steam page.
