Bills Must Be Paid is an incremental game built around an unusually physical-sounding financial loop: smash piggy banks to earn money, then use it to pay bills. Each strike costs stamina, and when your hand grows tired, the run ends. Bills left unpaid threaten bankruptcy, so deciding when to focus on smashing and when to settle debts gives the basic loop its pressure.
Paying bills also earns perks that help speed up future repayments. Bankruptcy feeds into progression rather than ending the whole arc: it awards legacy points for rings and bracelets that upgrade your hand. Piggies add variety to the earning stage, with types that flee, barely move, or carry black money, while their random loot makes each target uncertain. A branching skill tree offers upgrades to grip strength, luck, and other abilities, including rock rain and an electrified hammer.
Hammer choice adds another layer of build preference, trading factors such as critical chance, speed, striking radius, and damage. The listed format is single-player, with save-anytime support and play-at-your-own-pace features. The result is a compactly described cycle of earning, repayment, upgrades, and recovery after bankruptcy.
