Nonograms Katana: Sharpen your mind! Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, "Paint by numbers" and other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture. The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of "4 8 3" would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups. To solve a puzzle, one needs to determine which cells will be boxes and which will be empty. Determining which cells are to be left empty (called spaces) is as important as determining which to fill (called boxes). Later in the solving process, the spaces help determine where a clue (continuing block of boxes and a number in the legend) may spread. Solvers usually use a dot or a cross to mark cells they are certain are spaces. It is also important never to guess. Only cells that can be determined by logic should be filled. If guessing, a single error can spread over the entire field and completely ruin the solution.

Word Rush

Read full description

Word Rush is a tile-matching word puzzle where every word has been split in two — and it's your job to put it back together. SUN + FLOWER = SUNFLOWER. Simple, right? Not when the tiles are buried in layers, your slot bar only holds seven, and one wrong tap can block your way out. HOW TO PLAY Tap any uncovered tile to move it into your slot bar. Collect both halves of the same word and they snap together and vanish. Clear every tile to win — but if your slots fill up before you match, the round is over. Easy to learn, tricky to master. 100 HANDCRAFTED LEVELS Climb from breezy warm-ups to brain-bending late levels. Boards grow larger, layers stack deeper, and slots get tighter as you go. Every level is guaranteed solvable — if you're stuck, it's not the board, it's the plan. DAILY CHALLENGE One fresh board every day — the same board for everyone. Come back daily to keep your streak alive and collect your check-in coins. TIME ATTACK Race the clock in 90-second score runs. Chain matches fast and see how high you can push your best score. SMART BOOSTERS Stuck in a corner? Use Undo to take back a move, Shuffle to remix the board, Set Aside to park tiles, Hint to reveal the next step toward victory, or Revive to keep a great run going. WORD COLLECTION Every word you match is saved to your collection book. Watch it fill up as you play — can you collect them all? MORE TO LOVE Clean, colorful design with satisfying sound and haptics Relaxing background music Share your best runs with friends Quick sessions, perfect for a coffee break Family-friendly and great for learners of all ages Whether you're a puzzle fan chasing level 100 or a word lover growing your vocabulary, Word Rush turns spare minutes into smart fun.
