Welcome back, evolved one.
Your 3-day trial is the warm-up. Unlock once to guess the word and keep playing — forever.
Right guess: bonus, badge, eternal glory. Wrong guess: natural selection gently trims your bonus. Your letters survive — we're not monsters.
300,000 years of evolution, condensed into a five-minute daily habit.
🗓️ One word a week. Every week a new mystery word crawls out of the cave. It sticks around Monday through Sunday — same word all week, so there's no rush to out-run it.
🧩 Three challenges a day. Each day brings three bite-sized brain-teasers — anagrams, odd-one-outs, riddles and micro-trivia. Nail all three and you light up one letter of the week's word. Miss a day? No letter. Evolution waits for no ape.
🔠 Letters add up. Do your dailies and the word slowly reveals itself, one glowing tile at a time. We keep the last letter hidden on purpose — that final leap is yours to make.
🎯 Guess whenever you're feeling clever. Think you've cracked it? Take your shot. Guess right and it's confetti, badges and eternal glory — plus a brand-new word appears on the spot, no waiting for Monday. Guess wrong and natural selection gently trims your bonus (your letters survive — we're not monsters).
🌅 Sunday is reveal day. If the word outlived you all week, we put it out of its mystery on Sunday and tell you its story. A fresh word rises Monday.
🔥 Keep your streak. Play each day and your fire grows. Skip a day and it fizzles — so does your ancestors' respect.
🆓 The first 3 days are on us. Play free for three days to feel the rhythm. On day two we'll ask you to make a quick account (so your streak and progress follow you everywhere). To guess the word and keep playing beyond the trial, it's a one-time CHF 5.50 — no subscription, no ads, yours for good.
🧠 Why bother? Because every answer sneaks a little real knowledge into your skull. You came for a word game; you'll leave slightly smarter. Sneaky, we know.

You're responsible for keeping your login secure and for activity under your account. You may delete your account at any time from the account menu, which permanently removes your login.
2a. Purchases. Guessing the word and continuing past the trial require a one-time unlock of CHF 5.50.
