About this deck

Twenty-eight questions across the whole scientific waterfront: space, animals, chemistry, physics, and the weirder corners of the natural world. Four options each, one correct, instant feedback, and a report at the end that shows your score, accuracy, best streak, and every question you missed with the right answer attached.

Science trivia is satisfying because the answers are checkable: no judgment calls, no "technically both." A shark either has bones or it doesn't (it doesn't; the skeleton is cartilage). Water boils at 100°C at sea level whether or not you remembered it. Every question in this deck has one defensible answer, and the wrong options were written to be tempting rather than absurd, which is where the fun lives.

This deck works as a solo knowledge check, a classroom five-minute opener, or ammunition for deciding who in the group actually paid attention in school. Miss a few? The review list at the end is short enough to actually read, and a retake reshuffles the answer order so you can't coast on position memory. Your best score sticks around in your browser.
