What's the same
Both tile a grid with non-overlapping rectangles, one clue per rectangle, where a number gives the area. You are done when the whole board is covered with no gaps and no overlaps.
How Inlay differs
Inlay adds shape glyphs — square, tall, wide, or free — so a clue can constrain the shape as well as the area, or the shape instead of the area. It ships a daily, an archive, and practice sizes in the browser with no login.
Verdict
Shikaku solvers will recognise Inlay immediately, with shape clues and an archive added.
Free and the Arcade Pass
The daily board and ordinary practice are free. The optional Arcade Pass is a one-time $4.99 purchase for extra hints, a 60-day archive, and expert practice.
