NeuralRun · Daily mini-games
Free brain training games for your daily warm-up
A growing suite of free browser mini-games, each built around one cognitive skill — quick to learn, quick to play, designed as a daily mental warm-up. The lineup today: Misfire for reaction speed and impulse control, Swarm for number sense, and Glow Grid for visual working memory — plus Marathon, which runs all three back to back for a single Brain Score.

All three, one score
Every game back to back for a Brain Score.
One skill per game, by design
Every NeuralRun mini-game isolates a single cognitive skill — reaction speed, impulse control, number sense, and more as the suite grows. Rounds stay short and mechanics stay deliberately different, so a daily session can rotate between distinct mental muscles instead of grinding one.
The suite is built to expand: each new game targets a skill the current lineup doesn't cover yet, and every game keeps its rules free forever.
Today's lineup
Misfire
Tap the right targets and freeze on the traps as the pace climbs. It exercises reaction speed and impulse control.

Swarm
Two swarms flash for a blink. Pick which side had more to exercise rapid estimation and number sense.

Glow Grid
Squares light up one at a time. Tap them back in order — then backwards as the run deepens. It exercises visual working memory.

Marathon: one score, three skills
Marathon runs all three mini-games back to back in one sitting and returns a single number: your Brain Score. Misfire and Swarm run 60 seconds each, Glow Grid runs 8 rounds, and the three leg scores add together into the total.
There are no lives in Marathon. A mistake subtracts points instead of ending the run, so a session lasts the same length whether or not you are sharp that day — the players who most want the practice are no longer the ones ejected first. The end screen breaks the total down leg by leg, naming your strongest skill and the one with the most room to gain.
Daily
One run per day on the same three legs everyone else gets, ranked on a shared board.
Endless
Unlimited replays with freshly random legs each run, on its own all-time board.
Brain Score
One number spanning reaction, number sense and working memory — comparable day to day.
Why short daily sessions
A short game is easier to fit between real tasks. Switching mechanics keeps the warm-up varied, while modest expectations keep the purpose clear. These mini-games exercise the skills inside each round; they are a warm-up, not a miracle or medical intervention.
Fits real life
A quick round can sit between quizzes, meetings, classes, or study blocks.
Variety beats repetition
Alternate reaction-and-restraint rounds with rapid quantity estimates and sequence recall.
A warm-up, not a miracle
Use the games to exercise specific play skills, with no medical promises attached.
FAQ
What is Marathon?
Marathon runs all three mini-games back to back in one sitting — Misfire, then Swarm, then Glow Grid — and adds the three leg scores into a single Brain Score. It has no lives: mistakes cost points rather than ending the run. Daily plays the same legs for everyone once per day; Endless is unlimited replays with random legs.
Are NeuralRun's brain training games free?
Yes. Every mini-game in the suite is free to play with a free NeuralRun account, and the game rules stay free forever.
What do the mini-games train?
Each game in the suite targets one cognitive skill. In the current lineup, Misfire exercises reaction speed and impulse control with a tap-or-freeze mechanic, Swarm exercises number sense with rapid more-or-less estimation, and Glow Grid exercises visual working memory by having you tap back a sequence of lit squares.
Will more brain training games be added?
Yes. The suite is built to grow, with each new mini-game targeting a different cognitive skill. New games appear on this page and on the NeuralRun dashboard when they launch.
Do brain training games actually help?
Short, varied practice can sharpen the specific skills you play — reaction speed, impulse control, quick estimation. Treat them as a daily mental warm-up, not a medical intervention.
Do I need to download anything?
No. NeuralRun mini-games run in the browser on desktop and mobile.
