About Quadrix
Quadrix is a high‑tempo deck‑building roguelite that mixes block‑puzzle placement with chaotic card synergies. Each run gives a fresh deck, and every block you place can trigger board‑collapsing effects, gravity shifts, or explosive score multipliers.
Beyond the core runs, the game offers a 100‑level campaign, six distinct modes, local and online multiplayer, a block‑style workshop, and full Steam integration such as achievements, leaderboards, and cloud saves.
01 / THE GUIDE
Core Deck‑and‑Block Mechanics
Every placement on the grid carries lethal risk and potential reward, letting you reverse a catastrophic collapse in a single frame. Card combos can rewrite the board’s physics, turning a near‑Game Over into a chaotic comeback.
The deck is rebuilt each run, encouraging players to draft cards that either reward precise play or embrace tactical chaos. Sacrificing space can unlock powerful combos that boost scores dramatically.
- Observe how a card’s effect interacts with the current grid before committing a placement.
- Experiment with high‑risk drafts to discover unexpected score chains.
02 / THE GUIDE
Mastery Mode
In Mastery Mode the deck dictates the board’s physics, so speed alone won’t keep you alive. True mastery means timing pushes to the brink of collapse to trigger flawless, law‑breaking combos.
Players must learn exactly when to trigger cards at the absolute limit, using the deck to shape gravity and board behavior for maximum effect.
- Practice timing pushes in lower‑risk runs before attempting Mastery challenges.
- Focus on cards that manipulate gravity for more control over the board.

Game Modes
Quadrix includes six intense modes: Sprint, Ultra, Zen, Survival, Cascade, and Hardcore. Each mode tests mental limits with its own pacing and objectives.
Modes range from relaxed (Zen) to unforgiving (Hardcore), giving players varied ways to experience the deck‑and‑block system and to chase high scores on leaderboards.
- Start with Zen to learn card interactions without pressure.
- Try Survival to gauge how long your risk‑reward builds can endure.

Multiplayer Options
Quadrix supports local and online 2‑player matchmaking for both PvP and co‑op play. Players can compete head‑to‑head or survive together, using the same deck‑building mechanics.
Shared/split‑screen options let friends play on the same device, while cross‑platform multiplayer expands the pool of potential opponents and teammates.
- Use co‑op to coordinate card combos that would be too risky solo.
- Experiment with PvP to learn how opponents exploit board physics.

Piece Workshop & Avatar Editor
The Steam Workshop lets players design custom block styles, while the Avatar Editor offers visual personalization. These tools let you flex a unique look.
Custom pieces can be shared with the community, adding a creative layer beyond the strategic deck‑building core.
- Browse the workshop for block styles that match your aesthetic preferences.
- Use the avatar editor to create a visual identity that stands out on leaderboards.
