The skill behind speed
Enhance processing speed and reaction time. Every game in this category is built around that one skill, so your score reflects a focused measurement rather than a blurry average.
Processing speed and reaction time
Fast visual scanning and search
Quick, accurate decision-making
8 speed games
Each game adapts its difficulty to you and scores every session.
Pulse
Tap right if the new shard shares its colour OR shape with the previous one.
Bolt
Tap the equation that equals the target — fast, before the bar runs out.
Surge
Tap a lane to surge there. Collect halo-coloured orbs, dodge red shards, plan 5 rows ahead.
Halo
Keep your eyes on the core. Sparks bloom around the halo — tap the one that matches the cue’s shape AND colour.
Sprint
Tap the numbers in order, 1 to N. Fast as you can — and ignore the higher decoys.
Cascade
Tap each falling tile in the glowing colour the instant it hits the line — never a blank lane or a wrong colour, and the floor keeps speeding up.
Quartz
Rotate and drop the falling crystals to clear lines — read the queue and set up big clears before the floor speeds up.
Ascend
Bounce ever higher — steer onto the platform the rule calls and skip the traps as the floor falls away.
How speed feeds your score
Behind every game is a per-skill rating that adjusts as you play. Your Speed rating is one of six that roll up — by a fixed weighting — into a single Brain Fitness Index from 0 to 100.Speed contributes roughly 15% of that number, so progress here moves your overall index.
