Sudoku Guardians

Most sudoku apps hand you the answer. Sudoku Guardians teaches you how to find it. WHY, NOT JUST WHAT Tap the Coach and you get a nudge first — "Look at row 4. One number has only one place left." Still stuck? The Coach names the technique and explains the logic in plain words: "In row 4, 5 is blocked from every other empty cell, so 5 goes here." That's a Hidden Single. Next time you'll spot it yourself. Eight real sudoku techniques, explained the moment they matter: Last Number Left · Only One Spot · Locked in a Box · Locked in a Line · Matching Pair · Hidden Pair · Matching Triple · X-Wing RAISE A LEGENDARY GUARDIAN Choose a Golden Dragon, Phoenix, White Tiger, Griffin or Leviathan. It starts as an egg and grows every time you solve a puzzle — hatchling, juvenile, adolescent, adult, and finally its legendary form. Six illustrated stages for each creature.
