Debt & Credit

Keep a running balance steady inside a safe band by playing credits and debits — easy at first, until the swings start to grow.

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.

Game modes

• Daily: the same deal for everyone, in Easy, Medium, or Hard.

Controls

• Phone & tablet: tap cards to add or remove them, then tap End round.

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.
