Power down a circuit board by tapping junction nodes in the correct sequence to deplete all electrical charge safely. A wrong tap sends a surge backward through the circuit, charging already-depleted nodes. Later boards have eight active circuits simultaneously, each requiring its own depletion sequence without cross-interference.

Navigate a shadow maze where only a small circle of light around your character reveals the path. Tap to move through dark corridors and avoid shadow monsters lurking in the darkness. Brief light flares appear and illuminate the entire maze for two seconds — memorise the layout before darkness returns and the monsters reposition.

Guide a charged particle through a magnetic maze by tapping to switch polarity and attract or repel maze walls. The particle drifts between taps — anticipate position two seconds ahead. Rare neutral zones allow free movement for three seconds. The maze grows more complex with stronger fields deflecting your particle further.
