Mr. Logic's "Harder 4-Digit Puzzles"

Homepage

Welcome To Mr. Logic's
"Harder 4-Digit Puzzles!"

This game consists of a series of levels, each of which contains a different "secret rule" by which a given 4-digit number changes into another 4-digit number. When you figure out what that rule is, you will advance to the next level.

The instructions for playing are exactly the same as they were for the first "4-Digit Puzzles " game. (If you haven't already played that first game, you might want to do so before attempting this one. )

The object of this game is to try and reach level 10. If you get there, you will be given a secret password. If you are one of the first ten players to email that password to Mr. Logic, your name will be added to the game's Top Ten List.

Mr. Logic's "Harder 4-Digit Puzzles" game can be played either in full-screen mode, or in a window*. Just download and unzip the corresponding "harder" folder:

Download the "harder" folder (full-screen mode)

Download the "harder" folder (window mode)

Then double-click the "play.exe" file that you find inside the unzipped "harder" folder.

*[The windowed version the game is still in its Beta testing phase. If you experience any kinds
of problems (or even if you don't ), please let us know one way or the other. Thank you.]

(Mr. Logic's "Harder 4-Digit Puzzles" game was created entirely with SiMPLE using its "Drag & Drop" mode of operation.)

"Mr. Logic" is the producer of many online puzzle games. In the Spring of 2002, he created the concept of the "Online Riddle" when he released his Cybertrek adventure game. Since then, hundreds of other game makers have implemented his "URL-completion" method in the design of their own games (e.g., "This Is Not Pr0n", etc.).
