PolarFlipNest

PolarFlipNest is a vertical currency combination puzzle mobile game that combines timed decision-making with multi-rule sum-building gameplay. Players select coins and banknotes from the money house selection area and place them onto a tray to make the exact amount required by the level. They must handle various rules such as minimum number of pieces, odd/even count, unique denominations, avoiding counterfeit notes, making change, weight limits, picking from smallest to largest, paired equal values, mixing coins and banknotes, specified item counts, three types of metal, flash-memory money house, and post-overage correction. Correct combinations build combo bonuses and gradually increase difficulty; running out of time or violating rules ends the round. The interface provides clear, verify, pause, and help functions. The rules are clear and the controls lightweight, yet the challenge escalates between pressure and strategy.
