CubeForge
A speedcuber's workshop for ages 15–18 — a practice timer with inspection and Ao5/Ao12/PB stats, a 3-D algorithm explorer, 16 Concept kits (notation → CFOP → BLD → variants → FMC), and a written coach that walks real speedcubing decisions. On-device; works signed-out.

#4457c9 Characters who teach
Meet the cast
CubeForge's characters are realistic speedcubers, not mascots, and each one shows one solving skill: planning the cross, looking ahead, recognizing patterns, other methods, blindfold solving, reading your own times, bigger puzzles and fewest moves. Solvane, the mentor, teaches planning before you turn, and growth over ego.
Basalt
Efficient cross planning — a minimal, planned base
Kairo
F2L look-ahead — tracking the next pair
Cardan
OLL — pattern → algorithm recognition
Cyclo
PLL — permutation cycles → algorithm
Solvane
inspection/planning; growth over ego
Roan
Alternative systems (Roux/ZZ) — more than one correct method
Mnema
Blindfolded — letter-pair memory & spatial encoding
Torsa
Statistics & deliberate practice — read your own data
Manifold
Variants — generalise the method to big/non-cubic puzzles
Opta
Fewest moves — optimality & patient search
What's inside
Learning goal
A speedcuber's workshop for ages 15–18 — a practice timer with inspection and Ao5/Ao12/PB stats, a 3-D algorithm explorer, 16 Concept kits (notation → CFOP → BLD → variants → FMC), and a written coach that walks real speedcubing decisions. On-device; works signed-out.
Question kits
16 curriculum-aligned question kits, 0 questions in all, mapped to recognized standards.
On-device AI mentor
FoundationModels-powered hints, feedback, and adaptive difficulty — all running locally.
Mentored by Solvane — on-device AI, no data leaves the device.
How CubeForge handles your kid's data
- ✅ All progress, settings, and AI-generated content stays on the device
- ✅ No analytics, no tracking, no third-party SDKs
- ✅ Free — no ads, no in-app purchases
- ✅ No personal information collected from children — in line with COPPA (updated by the 2026 FTC amendments)
- ✅ No chat with strangers — play-together rooms use a short code and preset emotes, never typed messages
CubeForge runs on ForgeKit — the open-source Swift Package Manager framework that powers every Spark & Anvil app. ForgeKit ensures consistent accessibility, COPPA compliance, and design language across the portfolio, so your kid's progress and preferences feel coherent across every app they touch.
