CCA
Your display name, city and score will be public. Use a nickname if you prefer.
Tap the game or press Space to drop a battery—it keeps moving sideways as it falls. Stack them carefully: a missed landing or toppled tower ends your run.
Each successfully stacked battery adds its cold cranking amps (CCA) to your score. Make the top nine to add your name and city to the leaderboard.
