Flaskwell: Fair Water Sort

Flaskwell is a calm water sorting game with one simple promise: every level is fair. Tap a bottle, tap another, and pour until each glass holds a single color.

FAIR BY DESIGN
• Every level is checked by a solver before you ever see it
• You never need an extra bottle – a spare bottle is only an optional help, and that level then gives at most 2 stars
• Unlimited undo and free restart, never behind a video
• Dead-end warning: if no solution is left, the game tells you, and the rescue point jumps back to the last solvable moment (free once per level)
• Par is the fewest possible moves, so three stars really mean something

PLAY YOUR WAY
• Levels: endless, from 2 colors up to 12, with a Hard level in every ten
• Daily Puzzle: the same bottles for everyone, a calendar and a streak
• Optional daily reminder: one notification at the time you choose, only if today's Daily Puzzle isn't solved yet
• Streak shield: every 7 days in a row earns one, and it saves your streak if you miss a single day (hold up to 2, 3 with Pro)
• Hidden Colors: only the top layer is visible. Every hidden board is checked to have no dead ends, so you can always finish it (unlocks after level 25)
• Weekly goal: beat your own last week, not a fake rival

MADE FOR EVERY PLAYER
• Color-blind friendly: each of the 12 colors has its own shape (on by default)
• Smart hints show the solver's next 3 moves – 3 free hints every day, up to 5 more a day by watching a video
• Hand-guided start: on level 1 a hand shows your first pour, and a short bubble explains each new mode
• Dark Lab theme, AMOLED Night and a light Pastel theme for free
• Glassy bottles, realistic pours and a cork that pops onto every finished bottle
• Your profile: pick a name and an avatar, unlock more as you progress

OFFLINE, NO ACCOUNT NEEDED
• No sign-up and no internet needed to play
• Optional Google Play Games: achievements, leaderboards and cloud save for your progress
• Unfinished puzzles are saved, continue any time
