Number Hunt
Nine cells, one digit missing, the clock running. The simplest one to explain and the hardest to beat your own time on.
What you are training
Left side, right side
Both halves, talking faster
Letters and digits are handled by different networks in the brain. Pair Hunt puts them side by side and makes you switch between them under time pressure.
Hold, then place
From a flash to a memory
A letter appears for a moment and is gone. Holding what you saw, and the square it was in, is exactly the step where a passing impression becomes something you can still use seconds later.

Attention that filters
Nine digits belong in the grid; only eight are there. Number Hunt trains you to sweep past everything you can see and react the moment you spot the one that is missing.
It starts as a game. Rounds are short, you watch your own times improve, and that happens because you are playing.
