Daily Brains: a few small boards all obey a hidden law. Work out the law, then change as few squares as allowed so the workbench breaks exactly ONE of its clauses: not zero, not two. Each test only tells you how many clauses broke, never which. Easy has one clause; Genius has three, with symmetry, exceptions, nested rules and odd arithmetic. Every law is machine-checked so the examples pin down the answer and a random change almost never works. Four tiers a day, four handmade Classics, and endless Practice. For fans of induction games in the Zendo and Eleusis tradition.
