983 logic cells: too few for density figures, which are given for projects of 1,000 or more.
Every figure here is measured from the public layout, the same way for every design on the chip: see data and method, and how its designs used the process.
A minimalist single-button endless runner game inspired by the Chrome Dinosaur game, rendered on a single 7-segment display. Features an LFSR of 32 bits, Hardware Difficulty Selector, and a High Score memory.

Tiny Tapeout and wafer.space are independent companies that work together (announcement). Tiny Tapeout runs its own shuttles: it takes the projects, builds the die, and sells and supports the chips and boards. wafer.space has the dies manufactured on its GF180MCU runs, and these pages are wafer.space's measurements of them.
