CornerstoneQuest
A 3-minute daily island puzzle for ages 9–14: on a fresh Gullwick island, find the best corner for your first cottage — the one decision that shapes the whole game. Rank the spot by its pips, its mix of goods, and its room to grow, then compare with the surveyor. On-device; no clock, no pressure.

Meet the cast
CornerstoneQuest's cast are the founders of Gullwick, each embodying one placement idea; surveyor Idris ranks every corner and asks “where would your first cottage do the most?” Illustrated portraits & chapters are a paid-gen follow-on (STORY-PEND).

A good mix — three different goods beat the same good three times

Senna
The scarce good — seek the island's rarest resource; everyone will trade for it

Read chapter →
Anja
Room to grow — leave open neighbours to expand; never box yourself into the coast
