AlcumusForge

AlcumusForge's adaptive-mastery cast operationalizes the math-circle posture: a librarian-detective who knows the practice graph, a gentle hint author, a slow tortoise keeper of the practice room, a warm anti-anxiety streak presence, and a wider-than-you-think reframer.

Level 1

Adaptive Ladder

The heart of AlcumusForge, rebuilt for the browser. Each round it looks at what you know and offers three problems — Extend (right at your edge), Consolidate (something slipping), Stretch (newly unlocked) — voiced by your guides. It learns from every answer, on this device.

Fix-It Review · new on the web

Every problem you miss lands here so you can come back and fix it. Mistakes are a map to what to practice next — a correct re-try clears it from the queue.
