If you see nothing but a black blank screen, you just need to click on the blank screen once to make the game load. (Of course, give it some time, so the game can load.)
What to do in the Puzlogic Plus game?
Puzlogic is based on logic in how you set the numbers. A number cannot be repeated in the same row vertically or horizontally.
Drag the number to the correct box to solve the puzzle. However, if you drag it to the wrong box, don’t worry, you can rearrange them anytime you like. It can be rearranged unless you get it right.
