Hex Stack Atelier

Hex Stack Atelier is a portrait native color puzzle set inside a bright anime sketchbook. Choose one of three layered hex swatches, drag it onto an open honeycomb cell, and watch adjacent matching top colors transfer across shared edges. Build a clean eight-layer color stack to stamp it away and complete the page targets before the queue runs out.

Explore 19 authored sketchbook challenges with compact one-hand sessions, deterministic transfers, chain reactions, and increasingly tight color goals. Normal play and retries always work at zero brush tokens. Optional guides cost one brush token, while the clearly labeled Home AD control grants three tokens only after the rewarded callback succeeds.
