Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Hints now guide you through clear reasoning steps and take your notes into account. All room corners are highlighted consistently. Thinner outlines and larger notes make the board easier to read, while small and medium puzzles make better use of your screen. The object guide now lists objects you can place characters on first. This update also includes localized character names, corrected character sizes, eight iPad screenshots per language, and an optional rating prompt. Share your case card together with your result and the GridCase App Store link.
