The catalog
Every game trains one function and wears its colour. Memory, working memory, attention, processing speed, mental flexibility and spatial reasoning — no filler minigames.
Short-term and visual memory — pairs matching, the Corsi block-tapping test, and one-flash pattern recall.
The tasks working-memory research is built on: dual n-back, the digit span test, and mirrored spatial span.
Inhibition and focus under pressure — the Stroop test, go/no-go response control, and multiple-object tracking.
Raw speed with accuracy — Schulte table number sprints, symbol decoding, and useful-field-of-view scans.
Cognitive flexibility — switching rules mid-stream, hunting hidden rules that shift, and design fluency on a timer.
Spatial reasoning — mental rotation, perspective taking, the classic paper folding test, and path planning.
The source material
These aren't invented minigames — they're the tasks cognitive psychology has used for decades, made fast and playable.
John Ridley Stroop showed that reading a colour word interferes with naming its ink. Tapping the ink — not the word — trains selective attention and inhibitory control. In the app: Stroop.
Philip Corsi’s block-tapping task is still how researchers measure visuospatial memory span. Watch the blocks light up, tap them back, one more each round. In the app: Block Recall.
Jaeggi and colleagues made dual n-back the most-studied working-memory trainer: hold two streams in mind and match what appeared N steps back. Difficulty adapts to you. In the app: Dual N-Back.
Psychiatrist Walter Schulte’s scrambled number grid trains visual search speed and peripheral vision — a favourite of speed readers. Find 1 to 25 as fast as you can. In the app: Number Sprint.
The digit span test has anchored intelligence scales for over a century: hold a growing string of digits, then recall it — hardest in reverse. In the app: Digit Span.
Pylyshyn’s multiple-object tracking paradigm tests how many moving targets your attention can follow at once. Targets flash, roam, and hide among decoys. In the app: Swarm Track.
The honest fine print: training reliably improves the skills you practise — your span, speed and accuracy on these tasks. Whether gains transfer broadly to everyday intelligence is still debated in the literature, which is why Brain Games shows you real, per-task numbers instead of a made-up "brain age".

The habit loop
Three games from three different cognitive skills, picked fresh every day — about ten minutes. Finish all three for a +100 Brain Points bonus.
Every session earns Brain Points; a day streak multiplies them up to 1.5×. Levels and ranks — Rookie to Legend — make progress visible.
A global weekly board, plus points and best-score boards for every single game. Climb with a username you pick — weekly and all-time.
Span, accuracy, reaction time and interference cost, tracked per game. Watch the numbers researchers actually measure move over time.

Questions
Practice reliably improves the skills you train — span, accuracy, reaction time. Whether that transfers broadly to everyday intelligence is still debated in the research, so we track the honest numbers and skip the miracle claims. Consistency beats intensity: ten minutes a day is the sweet spot.
Free to download, and all 19 games are playable free — daily workout, streaks and leaderboards included. An optional Pro subscription adds trend charts, bigger Memory Match boards and premium card packs.
A working-memory task where you track two streams at once — a position and a sound — and respond when one matches what appeared N steps earlier. The app uses the adaptive Jaeggi-style protocol: get better, and N grows.
About ten minutes: three short games from three different cognitive skills, rotated daily so no skill gets left behind. You can also pin your own three favourites.
