A physics rebuild of 8-ball pool: drag distance folds into 18 power levels, all-stopped settlement keeps the rules trustworthy, and AI aim error keeps it alive.
A bubble-shooter teardown: aim angle folds into a column pick, 8-way pops raise density, and a ceiling drop every 10 shots makes pressure countable.
A 5-round penalty duel compressed into an angle-by-power table: three judgement bands — miss zone, risk zone, sweet spot — rule goal, save or miss.
A minimal penalty shootout: angle and power feed a probability model, every miss scores for the keeper, and a five-round sprint decides the match.
