ShelfForge
Remember the chess tactics you've learned. A calm study shelf quizzes you on real positions — look, decide your move in your head, then reveal the strongest move and grade yourself. Spaced practice brings the hard ones back until they stick. On-device; nothing leaves this device; no account. Ages 9–14.

Meet the cast
ShelfForge's study crew (ages 9–14) each embody one study-science rule — the crew IS the method: recall the move before you peek, meet a position again just before you forget it, mix the tactics up, and let the ones you miss come back sooner. Mentor Curator keeps the shelf: little and often beats cramming, and a miss is information, not a verdict. (Illustrated portraits + chapters are a tracked follow-on — R-WEB-CLONE-SPAWN-TRACKED.)
Recall
Active recall — pull the move from memory before you peek; retrieving is what makes it stick
Spacing
Spaced repetition — meet a position again just as you're about to forget it
Interleave
Mixed practice — shuffle the tactics so you can't run on autopilot
Sift
The three-pile sort — the ones you miss come back sooner; the ones you've got rest
Anchor
The memory hook — tie each position to its one idea so it sticks
Ponder
Predict before you check — decide your move first; a wrong guess teaches more than a peek
Curator
(Mentor) — little and often beats cramming; a miss is information, not a verdict
