Sortlock vs Knotwork Puzzle

Sortlock is a colour-sort puzzle with a brain. Pour balls between flasks until each flask holds a single colour — the satisfying sort you already love. The twist: some balls are hidden under a "?", and you have to DEDUCE their colour before you move. No guessing, no luck — just clean logic. Every board is built by a solver that guarantees exactly one logical solution, so a hidden ball can always be worked out from the clues: colour counts, flask rules and the balls you've already revealed. Think Sort × Minesweeper × Mastermind, in one calm puzzle. 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 IT'S DIFFERENT • A real deduction layer — not another mindless tap-sorter. • Adaptive difficulty keeps you in the zone: the engine learns your pace and tunes colours, hidden balls and empty flasks to you. • Endless, always-solvable content — boards are generated on the fly, never a dead end. • Colour-blind friendly: every colour also shows a letter (R/B/G/Y…); hidden is "?". A BOARD FOR THE WHOLE WORLD • One shared Daily Board every day — the exact same puzzle for everyone. • 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.

Knotwork is a calm puzzle built on one simple idea: rotate the tiles until every line joins into a single, unbroken knot with no loose ends. There is no timer, no score chasing and no way to lose. You turn each piece, watch the golden strands find each other, and feel the whole pattern settle into place. When the last end closes, the knot lights up in a soft turquoise glow. The art is inspired by Anatolian and Celtic knotwork and the gold detailing of classical tezhib. Every board is a small woven ornament on deep petrol blue. FEATURES • Hundreds of levels that grow from gentle to genuinely tricky • Fully wordless, so it plays the same in any language • Relaxing pace with optional sound, music and Zen mode • Colored strands that weave over and under at higher levels • One hand play, perfect for a quiet minute anywhere • Plays offline, with no account and no sign up • Optional one time purchase to remove ads Sit back, breathe, and weave the endless knot.
