About this game
Sortlock is a colour-sort puzzle with a brain: sort balls into flasks, but some balls are hidden under a "?" — so you DEDUCE their colour with logic instead of guessing.
Every board is built by a solver that guarantees exactly one logical solution. A hidden ball can always be worked out from the clues — colour counts, flask rules and the balls you've already revealed. It's Sort × Minesweeper × Mastermind in one calm, satisfying puzzle. No timers, no pressure, no luck.
HOW TO PLAY
• Tap a flask, then another, to pour the top ball across.
• Make every flask a single colour to solve the board.
• Some balls are hidden ("?") — read the clues and deduce their colour.
• Every level is guaranteed solvable by logic alone.
WHY SORTLOCK IS DIFFERENT
• A real deduction layer — not another mindless tap-sorter.
• Adaptive difficulty that learns your pace and tunes colours, hidden balls and empty flasks to you.
• Endless, always-solvable boards — generated on the fly, never a dead end.
• Colour-blind friendly: every colour also shows a letter (R/B/G/Y…); hidden is "?".
A DAILY BOARD FOR THE WHOLE WORLD
• One shared daily board — the exact same puzzle for everyone, every day.
• Climb the daily ranking: fewest moves, then fastest time.
• No spoilers — share a clean result card and a unique link to your run.
ECHO DUELS — DEDUCTION, HEAD TO HEAD
• Race a rival's "echo": an asynchronous replay of how someone else cracked today's board.
• Get matched to your skill, or challenge a friend with a 6-character code.
• Win on fewer moves and tighter reasoning — no real-time servers needed.
CALM BY DESIGN
• No timers on normal play, no pressure, no dark patterns.
• Plays fully offline — the daily board and duels are the only online extras.
• Free to play: no ads and no in-app purchases in this version.
Sortlock is made for quiet, thoughtful moments: a coffee break, a commute, or winding down before bed. Sort blind, think it through, and find your flow.
