Football Kick: Compressing a Penalty Shootout into an Angle-by-Power Judgement Table
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.

Pull the Pin: Sequential Penalties and 'Fake Difficulty'
Deconstructing the penalty mechanics and fake difficulty design in pull-the-pin puzzles. The article analyzes how sequence errors trigger immediate restarts, leveraging low forgiveness to create a 'seemingly hard, actually fake' challenge experience. It reveals the underlying logic of building levels via rule-based constraints rather than complex operations, offering high-value design references for puzzle games.
