How to Play

Cipher Vault is a cryptogram. Decode the quote one letter at a time.

What this is: A quote is hidden behind numbers. Every time you see the same number, it is the same letter. Different numbers are different letters. Spaces and punctuation stay visible.
How to solve: Tap a numbered tile, then type a letter. That guess applies to that tile. Locked green tiles are already solved — one of every letter is already filled. Look at a filled T, read its number, find that number on an empty tile, and type T. Start with one-letter words (A or I) and tiny words like THE. Wrong guess costs a star. Soft hint shows number frequencies. Reveal fills one tile.
Gold coins: You start with 100 gold. Hints cost gold. Finish a puzzle to earn more. Gold follows how many letters are in the quote, so a longer quote pays more. Daily Vault is one extra puzzle per day. Optional Moon Bucks shop never required.
Rules: Start with 100 gold. Each puzzle pre-fills a few tiles. One of those letters is a vowel when the quote has one. Wrong guess = −1 star. 0 stars = wait 45s for 1 star, or spend 75 gold coins for 2 stars. A soft hint shows number frequencies and costs 10 Moon Bucks. Reveal fills one word and costs 5 Moon Bucks. Fill discovered is 40 gold per letter you already know, or 1 fill credit (10 credits = 4 Moon Bucks). Finishing with an item costs 25 Moon Bucks and pays no gold. A quote pays once. One you have already been dealt pays nothing, on every difficulty. Each puzzle starts at full value and every miss takes 10% off (it never drops below 10%). Perfect Clear bonus if you finish with no misses and no help. Gold coins you keep also give XP; fill the XP bar to level up. 100 gold coins = 1 Moon Buck. Daily Vault once per day with bonus gold. Keep a solve streak.

Rush sometimes appears at random when you tap Play (~1 in 8 games) — you cannot pick it. Same puzzle as Classic, plus a countdown that scales with how many letter tiles are still open (and difficulty). The clock stays ready until you type your first letter (starters do not start it). Finish with time left for a Rush bonus: full value (= 50% of puzzle gold / +25% XP) for the first quarter of the timer, then it falls linearly to 0 at time out. If the timer hits 0 you can still finish for normal gold. The Rush bonus is forfeited. Daily Vault and Tutorial stay Classic.
