New Feature
🧠 10 new memory & brain training tools
A 10-tool memory pack for the Psychology category — Memory Card Game with brain-fatigue, Simon-style Pattern Memory, daily date-seeded challenge, Method-of-Loci palace builder, and 6 more. All free, all client-side.
The Psychology Tools category just got 10 new memory and brain training tools. Each one targets a different memory system — visual, verbal, spatial, auditory, working memory — and most ship with a twist that pushes them past the usual clones.
What's new
- Memory Card Game — 4 modes (Classic, Time Attack, Hardcore, Infinite). Brain-fatigue mechanic: the longer you play, the faster mismatched cards flip back face-down.
- Number Memory Trainer — progressive digit span (3 → 5 → 10 → 20+) with a Flash mode (every number shown for only 0.5s) and a local top-10 leaderboard.
- Pattern Memory — Simon-style sequence game with synthesized tones per pad (Web Audio API) and haptic vibration on mobile devices.
- Word Sequence Memory — words flash one by one, then you pick them in order from a pool with distractors. 4 themes: Random, Tech, Games, Story.
- Visual Memory Grid — grid lights up tiles, you click them from memory. Grid grows from 3×3 to 8×8 across levels. 3 lives per run.
- Reaction + Memory Hybrid — go/no-go reaction test with a memory twist: tap on green, skip red, but two greens in a row also means SKIP.
- Sound Memory Trainer — audio Simon with three sound packs (Piano sine, Pixel square, Sci-Fi saw). Playable with eyes closed.
- Daily Memory Challenge — one 8-digit puzzle per day, deterministically seeded from the date so everyone gets the same. Streak resets if you miss.
- Chunking Trainer — teaches the 2–4 digit chunking technique (938472910 → 938-472-910). Scores how well your chunks follow the rule.
- Memory Palace Builder — Method-of-Loci trainer. Pick a room (Living Room / Kitchen / Bedroom), drop items onto objects, walk through, recall.
Highlights
- Pattern Memory and Sound Memory Trainer use the Web Audio API to synthesize tones in-browser — no audio assets to load.
- Daily Memory Challenge uses a Mulberry32 PRNG seeded from the date hash, so the daily puzzle is identical for every player on every device.
- Memory Palace Builder is the first Method-of-Loci tool here — drop your shopping list onto the kitchen sink, picture it vividly, recall through the spatial walk-through.
- Every tool stores best scores, streaks, and history in localStorage only. Nothing leaves your browser.
Head to the Psychology Tools category to try them. All 10 are free and unlimited.
