How it works
Block Count is built on a real limit of human vision: we can glance at a small handful of things — usually around four — and know the count instantly, no counting required. That instinct is called subitizing. Push past it and the brain has to switch to actually counting, one item at a time, which is exactly what a loose crowd of drifting blocks forces you to do. Each round sweeps a mix of red target blocks and grey, orange, pink or crimson decoys across the stage over a few seconds, entering from the left and exiting right — your job is to track only the red ones and land on the right total before they're gone.
Scoring rewards a genuinely close count, not just a perfect one: land on the exact number and the round scores a full 10. Miss by a little and accuracy is measured as the relative size of the miss against the true count — one block off on a sweep of 12 reds costs much less than one block off on a sweep of 6 — which then converts to a score out of 10, capped just under a perfect score so only an exact count ever reaches the full 10.
Difficulty raises the red count, adds more and closer-hued decoys, speeds up the sweep, and — on Hard — lets blocks cluster and overlap, while the true reds always keep a faint glow so the round stays hard, never unfair.
