MosaicForge
Tile-laying strategy for ages 9–14: place coloured tiles to score — a big same-colour CLUSTER, or a MOSAIC bonus for a tile that borders three different colours. Predict the best placement, then the engine reveals every cell's score. An original game; on-device; nothing leaves your device.

Meet your mentor
Every Spark & Anvil app has a friendly mentor character that demonstrates, asks, and patiently scaffolds learning.

Meet the cast
MosaicForge's cast each embody one tile-laying idea; mentor Tessa sets the board and asks “where does this tile score the most?”
Clara
The cluster — link same-colour tiles into one big region; size is the score
Bridget
The bridge — one tile can join two separate groups into a single wall
Mira
The mosaic bonus — a tile touching three different colours earns extra
Otto
The optimiser — weigh cluster against bonus; the biggest TOTAL wins, not the biggest region
Perry
The planner — think a move ahead; where you place now shapes what scores later
Tessa
sets the board and asks where the tile scores the most, and why

How MosaicForge 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
MosaicForge 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.
