Coloreku: Queens Sudoku Puzzle

Coloreku: Queens Sudoku Puzzle brings two logic puzzles into one game: Queens-style sprout beds and a sudoku made of colors. Free to try, with no ads and no subscription. Pay once to unlock everything.
• 148 levels across three logic modes, plus a fresh bed every day
• Every bed and every level with blocks has exactly one solution: no guessing, just logic
• Hints that explain the next step, not just the answer
• Play offline, with no account and no ads

QUEENS WITHOUT ADS
Plant exactly one sprout in each row, column and colored bed. Sprouts cannot touch, even diagonally. Mark cells to rule them out and use deduction to find the right places. A sprout in the right cell locks in, and one in the wrong cell gets a red border right away.

COLOR SUDOKU
Swap the numbers for colors. Fill each row and column without repeating a color, from 2×2 to 9×9. In color sudoku, a mode with its own section in your garden, each color goes once per row, column and block, across four gardens from 4×4 to 9×9. That makes 32 color levels and 16 sudoku levels, and every level with blocks has a single answer.

GROW YOUR SKILLS THROUGH 100 LEVELS
Follow an eight-chapter journey through the beds, each chapter building on what you have learned. Progress from simple deductions to pairs, groups and short what-ifs, with lighter levels between the hard stretches so you can catch your breath. Earn stars for solving a level, finishing without hints and making no mistakes. Stars celebrate your progress; they never block the next level.

A FRESH DAILY CHALLENGE
Play the daily bed and build a streak. Difficulty grows through the week, from easy on Monday to expert on Sunday. For free play, choose a board from 5×5 to 10×10 and a difficulty from easy to expert.

FREE TO START, PAY ONCE
Start free with the first color levels, the first two color sudoku levels, the first two chapters of the beds journey and the daily bed. Enjoying it? Unlock the Full Garden with a single purchase and keep every level in all three modes and free play for good. No ads, lives or energy limits, and no subscriptions. Unlimited hints and full offline play, with no account required.

HINTS THAT EXPLAIN
Stuck? Ask for a hint that points out a conflict or explains the next logical step, in a bed, a row or a block. Undo and redo let you rethink your moves. Pause whenever you need a break.

A GARDEN FULL OF CHARACTER
Plant stickers give each color its own identity. Prefer geometric cues? Turn on Simple symbols. Coloreku also responds to Differentiate Without Color and Reduce Motion.

Keep track of completed levels, stars, daily streaks and personal bests. Play offline on iPhone or iPad, with no account required. Progress and preferences are saved on your device.
