Logic, numbers and words

Sudoku asks you to fill a 9 by 9 grid so that each row, column and box holds every digit once, with several difficulty levels. Merge Numbers is a 2048-style game: slide the tiles, merge equal numbers and aim for the biggest tile. The Blocks is a block puzzle on an 8 by 8 board: place shapes, clear full rows and columns and build combos, with no timer. Crosswords and arrow words test your vocabulary with clues to solve, in several languages.

Help when you need it, never forced

Hints, checks and saved progress are there when you want them, and each game page explains the rules and strategies in detail. Grids are saved as you play, so you can stop and come back later on the same device.

Play alone or together

Every puzzle game can be played as a guest. With a free Zlobby account, your progress and scores follow you between devices, and you can compare results on the leaderboards. Tic-tac-toe is played against the computer, with two players on the same device, or with friends invited through a link.
