Your first visual rule
Every ARC puzzle uses the same loop: compare input with output, name the rule, then apply it to a new test.
Start with one worked example, solve a guided test, then practice three useful tools. About a minute; no account required.

The idea behind the puzzles
ARC puzzles show a few input-and-output examples. Your job is to infer the rule that connects them, then apply that rule to a new grid. There are no instructions because discovering the instruction is the puzzle.
