A simple, no-build trainer for practicing blindfolded Rubik’s Cube letter sequences.
Made for fun, training, and possibly to live on jperm.net.
When solving BLD (blindfolded) you need to memorize long strings of letters that correspond to edge and corner pieces. That’s what this trainer does:
- ✅ Generates real edge and corner letter sequences
- ✅ Lets you pick edges only, corners only, or both
- ✅ Lets you set the length range (min/max letters) or use presets (Easy / Normal / Extreme)
- ✅ Supports different buffers
- ✅ Optional distraction task simple math problem before recall (to imitate distractions during a real solve)
- ✅ Records memorization time only (from reveal → “Ready”)
- ✅ Tracks accuracy, full solves, and last/median/average/best memorization times
- ✅ Light/Dark theme toggle
(open on your phone or desktop browser, nothing to install)
- Open the trainer.
- Pick your settings: edges/corners/both, buffer pieces, sequence lengths.
- Hit Start. Letters will appear.
- Memorize --> click Ready.
- If distraction is enabled, solve the math problem.
- Type your recalled sequence(s).
- See your accuracy and memo time.
- Hit Next round to continue, or Reset stats to wipe progress.
- The widget is one self-contained HTML file:
index.html. - Written in plain HTML + CSS + jQuery.
- Drop-in ready: paste the
<div id="blindTrainer">…</div>+<script>…</script>into any page that already loads jQuery. - Or embed as an
<iframe src="…/index.html">. - Stats are saved in
localStorage. No backend needed.
