Mystery-number riddles that always have a fair, findable answer
Riddle Realm is a free math riddle game built around the classic "mystery number" format: "I am a number. Multiply me by 3 and add 4, you get 19. What number am I?" Every riddle is generated so it's always genuinely solvable and fair, the mystery number is picked first and the riddle is built around it, not the other way around. Four multiple-choice answers are shown, and a Hint button offers a general strategy (work backward, undo the last step first) without ever giving away the actual answer.
There's no penalty for guessing wrong. A missed pick just asks you to look again at the same riddle, with no lost streak and no timer pressure. Six tiers scale the riddles from one-step addition or subtraction, through one-step multiplication or division, up to two-step riddles and a bigger-number championship.
A separate Daily Riddle tab gives every player the exact same riddle each day, solve it to keep a streak going, then copy a spoiler-free result to share, similar to how Wordle-style daily games work. Every solved riddle earns a gem, and collecting enough gems unlocks a new realm, from the starting Foggy Cave through Crystal Cavern, Starlit Grove, Moonlit Spire, and the Astral Sanctum. It's free, works with a mouse, touchscreen, or keyboard, needs no download or account, and saves your gems, best streaks, and daily streak locally in your own browser.
