try the first one
each puzzle shows four numbers in a sequence, and you guess the fifth. rules escalate from simple arithmetic to multi-step patterns as you go.
retry as much as you like, but only a first-try solve earns the diamond. wrong guesses are shown crossed out, and the rule is never revealed on failure, so every puzzle stays worth solving properly. this is the game's real puzzle 001.
