Suguru — also known as Tectonic or Kemaru — is a logic puzzle of pure deduction. Fill every region with the numbers 1 to its size. Two equal numbers may never touch, not even diagonally. That's all the rules there are. ENDLESS PUZZLES, MADE ON YOUR PHONE Every puzzle is generated on your phone, so you never run out. Seven sizes from 5×5 to 12×12, four difficulties from Easy to Expert. EVERY PUZZLE HAS ONE SOLUTION — AND YOU NEVER HAVE TO GUESS Each puzzle is checked by a solver before you see it: one solution, reachable by logic alone. Difficulty is set by which techniques the puzzle needs, not by how many numbers are missing. HINTS THAT TEACH Stuck? A hint shows you where to look first. Ask again for the name of the technique, then why it works — and only at the end the number itself. Take as much help as you want, and no more. • Cell hint: what can be worked out about the cell you have chosen. • Check: compares your numbers with the solution and rings the wrong ones. A DAILY PUZZLE The same puzzle for everyone each day, rising from gentle on Monday to a proper challenge on Sunday. Keep your streak going. MADE TO BE PLAYED • Numbers and pencil marks on one keypad — no mode to switch. • Select several cells at once and pencil a mark into all of them. • Pencil marks in fixed positions, like the five on a die. • Unlimited undo and redo. • Your unfinished puzzles are saved; pick up where you left off. • Statistics for every size and difficulty. • Colour themes, including high contrast and colour-blind-friendly region colours. • Danish and English.
