Immerse yourself in Shikaku, the elegant Japanese logic puzzle reimagined with tactile claymorphic design, responsive haptics, and a soothing acoustic soundscape.
Also known as "Divide by Squares" or "Number Area", Shikaku is a celebrated Japanese brain teaser that transforms pure mathematics into visual meditation.
THE RULES ARE DECEPTIVELY SIMPLE:
• The grid is populated with numbers.
