Switch between a fixed daily set, practice and a larger-or-smaller challenge. Mixed contains 12 unique questions; Insects and Everyday objects contain 6 each. Each question appears once in a set. Theme and mode cards open real games in the central board. Switching games keeps each set’s progress; returning or refreshing resumes it. Daily sets refresh with your device’s local date.
8 specific subjects: Nintendo Switch OLED, Nintendo Switch Lite, Atlas moth, Monarch butterfly, Steam Deck OLED, Kobo Clara Colour, Polyphemus moth, Cecropia moth. These are original recognizable silhouettes with body, wing or device structure. Every question scores the marked horizontal measurement; illustrated heights and poses are not measured data. Insect rounds explicitly compare published adult upper endpoints, because real individuals vary.
This is an independent Plainoku game inspired by sizeitup.games. Original code and drawings, no affiliation. The collection contains 12 source-defined comparisons. Left/right swaps and different starting sizes are not extra questions. An explicit replay uses these same questions.
