Chronodisk challenges in Re:Night—the tactical roguelike deckbuilder by Seahorse Games and HARRISONWORLD—are single-turn tactical memory puzzles tied to individual character progression. Rather than standard roguelike combat, each Chrono Shard puzzle places your hero in a predetermined board state where you must eliminate every target in a single round. Clearing these trials unlocks exclusive cards, items, and character equipment for future dungeon runs.
How the Chronodisk System Works
The Chronodisk functions as Re:Night's permanent meta-progression hub between expeditions. As you take characters like the Hunter, Farmer, and Rogue into the town and castle, completing runs or reaching milestones levels up each hero.
Leveling up grants access to unique memory fragments known as Chrono Shards inside the Chronodisk interface.
- Fixed Board States: Chronodisk challenges do not draw random cards from your roguelike deck. You receive a fixed hand, specific positioning, set energy, and predetermined enemy placement.
- One-Turn Objective: To clear the shard, you must find the exact sequence of moves, card plays, and elemental setups to defeat all enemies in one turn.
- Meta Rewards: Solving a Chrono Shard unlocks new character cards, passive equipment, and pool items for that class in subsequent runs.
- Memory Achievements: Completing all shard stages for a class unlocks that hero's dedicated Steam achievement.
Core Mechanics for Solving Chronodisk Puzzles
Every shard stage tests your understanding of a specific hero's core kit and the game's universal interaction rules. If you find yourself a few points of damage short, check whether you missed one of the following systems:
The Elemental Critical Triangle
Re:Night uses a strict elemental interaction loop:
- Fire deals multiplied critical damage against targets afflicted with Grass.
- Grass deals multiplied critical damage against targets afflicted with Water.
- Water deals multiplied critical damage against targets afflicted with Fire.
Stacking status counters before unleashing your primary attack is mandatory in multiple shard stages. If a puzzle enemy carries a Fire debuff, hitting them with Water damage doubles or significantly scales the output, which is often the only way to meet the required damage threshold before your turn ends.
Board Positioning and Environmental Objects
Tile manipulation is central to board clears. Field objects—such as stone walls, rocks, and ally projections—can either block movement or serve as damage multipliers. Certain cards, such as the Hunter's Achilles Shot or area-of-effect abilities, scale in power based on surrounding objects or require the card to be played from the exact center of your hand. In Rogue challenges, abilities frequently depend on whether an adjacent or opposite tile is occupied by an obstacle to trigger pincer attacks.
Solutions and Tactics for Early Shard Puzzles
While developer Seahorse Games provides official step-by-step documentation for every challenge stage in pinned community threads, the starter character puzzles focus on specific mechanical sequences.
Hunter Chrono Shard Puzzle
The Hunter's initial memory shard focuses on turning board obstacles into direct offensive power and triggering the Precision status.
- Convert Surrounding Objects: Use your setup abilities (such as Counter-Strike) to absorb the defensive rocks and obstacles surrounding the targets into raw temporary Strength.
- Activate Precision Triggers: Play support cards like Relax Hands to gain multiple precision trigger counts without expending unnecessary movement.
- Execute Center-Hand Shots: Arrange your hand so burst attacks—such as Close Shot and Achilles Shot—sit in the center position when played, activating their bonus multipliers to finish the remaining targets.
Rogue Chrono Shard Puzzle
The Rogue's shard puzzle requires precise spatial positioning, directional targeting, and cycling into Finale triggers.
- Position Swapping: Begin by using position-swapping skills to trade places with the target. This aligns you with the necessary flanking angle and sets up directional slashes.
- Apply Elemental Infusion: Use skills such as Lure to alter the enemy's elemental affinity (e.g., converting them to Fire).
- Trigger Directional Slashes: Execute attacks like Twin Slash while standing on the required flank.
- Charge and Trigger Finale: Finish with Finale Charge and directional follow-up slashes (Return Slash). Note that abilities like Return Slash only trigger their full damage bonus when initiated from the exact side specified by the card text.

Frequently Asked Questions
Can I retry Chronodisk challenges if I make a mistake?
Yes. Re:Night features an undo function and allows you to restart the puzzle stage at any time without penalty or resource cost.
Do I lose roguelike progression if I enter a Chronodisk challenge?
No. The Chronodisk is accessed outside active adventure runs. While you can abandon an active run to visit the meta menu, unlocked shards remain available to attempt whenever you choose.
How do I unlock shards for the Dancer, Scholar, and Shaman?
You must first unlock the characters themselves by clearing runs with starter classes (such as beating the game with the Farmer, Hunter, and Rogue), then earn class experience to generate their respective Chrono Shards.
