Keep a running balance steady inside a safe band by playing credits and debits, easy at first, until the swings start to grow.
Was this fun?
How to play
You hold a hand of signed transaction cards: credits add to your balance, debits subtract. Play and unplay cards to set your total, watching the live balance, then end the round to settle. Land inside the safe band, or exactly on a target, to survive and move on. Each round the numbers swing wider, so the arithmetic of staying in range gets tighter.
Credit cards (+) raise the balance; debit cards (−) lower it.
Toggle cards on and off to fine-tune your total before settling.
Settle inside the safe band, or exactly on the target, to advance.
Swings grow each round, demanding more careful combinations.

Tips & strategy
Add up your committed cards as you go so you always know how far you are from the band.
Pair a big debit with a big credit to make fine adjustments without overshooting.
Aim for the centre of the band, not its edge, to leave room for rounding in your favour.
