Master the Power of Logic in ON&OFF

Experience a revolutionary turn-based deckbuilding roguelike that redefines the genre. In ON&OFF, your strategy extends beyond the hand you are dealt; it is about how you orchestrate your board. Place magical cards on a strategic grid and master the art of signal management to trigger powerful, recurring effects.

Reactivate Cards to Multiply Your Impact

Unlike traditional roguelikes where cards are discarded after a single use, ON&OFF turns your board into a persistent tactical playground. Cards remain on the field, toggling between ON and OFF states. Every time a card transitions from OFF to ON, its effect triggers again. This unique mechanic allows you to stack damage by reactivating attack cards multiple times or layering defense for impenetrable protection. Your success hinges not just on your deck composition, but on your skill in positioning cards for maximum reuse.

Engineer Complex Signal Chains

Harness the flow of energy to dominate the battlefield. When a card activates, it sends magical signals to adjacent cards based on directional arrows. A well-placed signal can trigger a massive chain reaction across the entire grid. By carefully designing the layout of your cards, you can transform a single activation into a cascading flow of power, creating short, reliable combos or ambitious, board-wide chains that catch your enemies off guard.

Strategic Placement Is Your Core Tactic

In this game, spatial intelligence is your greatest weapon. Simply having strong cards isn’t enough to win; you must cultivate an environment where your existing cards work in harmony. Whether you are retriggering attack cards to finish off a boss or preparing a defensive wall for an incoming heavy strike, placement strategy is the heartbeat of your deck’s performance. Optimize your layout to bring out the exact effects you need at the perfect moment.

Build Your Custom Chain Engine

Every run through ON&OFF offers new opportunities to refine your playstyle. Collect cards through intense battles and construct a deck that fits your tactical vision. Will you focus on a key-card engine that repeatedly awakens a single powerhouse, a massive chain deck that wipes the screen in one go, or a resource-heavy setup that builds up cost for a singular, earth-shattering activation? The choice is yours.
