Build one position at a time
Begin with a single card, then add the next position. Each sector rebuilds the active cards so recall stays fresh and ordered.

Speed + Accuracy = SurvivalPractice changes when it feels like play
You already know memorizing a stack takes work. The game makes you want to do the work.
Instead of staring at a list or repeating the same drill, you build your fortress one card at a time. Then alien Raiders fire lasers, dive toward your defenses, and force you to recall every position under pressure. That controlled stress matters. It helps you practice retrieving the stack while your attention is being challenged, much like it will be during a real performance. The repetition is the point. Every return trip strengthens the stack and helps move it into long-term memory.
How Memory Fortress works
Learn. Defend. Strengthen.
Recall under fire
Alien ships attack in random order, fire lasers, and dive toward your fortress. Enter the correct stack number before they breach your defenses. The action adds controlled pressure that trains you to recall accurately even when the moment feels stressful.
Revisit the cards that need work
The game tracks response speed and uses your slowest cards as Elite Raiders, giving weak positions more attention in future battles.
