Clearer rules, and a board you can read without colour
• The walkthrough now opens on the three rules with a solved board beside them, so you can see what a finished puzzle looks like before the first step.
• Every mark on a board now differs in shape as well as colour — readable in sunlight, and without relying on colour vision.
• Japanese, Korean, Chinese and Thai text no longer falls back to empty boxes.
• Google Play Games stats, and the usual round of fixes.
