The apps for iPhone and Android have the same four daily puzzles plus a streak for full-panel days, and two more games: Wire Run and Ground Fault. A one-time unlock adds those games, practice boards in every size and every new game we add.
Open Circuit
Turn wire tiles until every device is wired back to the panel with no open circuits.
Silence
Each press flips a horn/strobe and the ones beside it. Silence the whole floor in as few presses as you can.
Resistors
Place one end-of-line resistor in every row, column and zone, with none touching.
Smoke Test
Check every room without opening one full of smoke. Every floor can be solved by logic alone.
