Watch the sequence, then repeat it back.

Sequence memory vs. spatial memory

This is a sequence-memory test, which is a genuinely different skill from the spatial memory used in a game like Memory Match — here you're recalling an order of events, not the location of a hidden item, and the two hold up differently as the challenge grows.

Most people top out somewhere around 7 steps trying to hold the whole sequence as one long chain in their head. Chunking helps: group the flashes into pairs or triples as they play ("top-left then bottom-right, then top-right") instead of memorizing four separate single steps — it's the same trick that makes a 10-digit phone number easier to hold onto in three chunks than as ten individual digits.

Easy mode is a good place to first learn the four tile positions without the added pressure of speed; once those feel automatic, Hard mode tests how well you can still track the order when there is barely time to register each flash.
