How to prepare for the Flashback game (2026)
Flashback tests working memory and sustained attention: you decide whether the shape on screen matches one shown a few steps earlier.

Shapes appear one at a time. For each one you answer a simple question: does it match the shape shown a fixed number of steps back? Get it right and the game speeds up or increases the gap, demanding more from your memory.
Strategies that work
- Hold a small rolling buffer of the last few shapes in your mind and update it each time.
- Don't overthink: react to the comparison, then immediately refresh your buffer.
- Practise n-back style tasks to build the exact skill this game measures.
