A calm memory game built for ADHD brains
Pattern Builder is a free Simon Says-style game that helps you train working memory, focus, and attention. Watch the sequence, repeat it back, and build your streak — one gentle round at a time.
How to play
Three simple steps. Pick a companion, watch the pattern, and repeat it back.
Watch the sequence
Your companion lights up a short pattern. Give it your full attention — that focused watching is the first rep.
Repeat it back
Tap the pattern in the same order. Holding a sequence in mind is direct working memory practice.
Build your streak
Each round adds one step. Clear feedback and gentle pacing keep it calm, not stressful.
Made for the way ADHD brains work
Designed to lower friction and reduce overwhelm, so practice feels doable on low-energy days.
Working memory practice
Watch, hold, and repeat short sequences — the core skill behind focus and follow-through.
One target at a time
A single pattern to follow means fewer distractions and an easier on-ramp into a flow state.
Gentle, short sessions
Rounds are quick. Play for two minutes or twenty — whatever your attention and energy allow.
Calm, low-stimulation design
Muted colors and simple controls keep the experience soothing instead of overstimulating.
Immediate feedback
Every round gives a clear result, so you always know where you stand without complex menus.
No account, no pressure

Grounded in research on focus and memory
Pattern games like this draw on well-studied ideas from cognitive science about how attention and working memory are built and practiced.
Studied with brain imaging
Modern ADHD research uses brain imaging to map attention and working-memory networks. See the latest research →
Attention is built by circuits
Scientists recently found brainstem neurons that act as a "focus filter," blocking distractions. Read the study →
Working memory can be practiced
Holding and repeating short sequences is a classic way to exercise working memory. Why it helps →
