I have a real bad habit of buying All-In-One applications.  Generally what you end up with is one application that has lots of half-baked programs.

I recently download All-in-1 Logic GameBox by AppZap.  I love logic games, and this is my favorite one so far.  The game has a clean interface, and most of the games are simple to understand and easy to use.

My only complaint, in the last update they took away the telescope game.  I hope they bring it back.

Version 1.5 includes eight games, with more than 2,000 levels:
Round Round!
Stickies!
Parking Lot
Labyrinth
Liquid Measure
Flip It
Arithmetic
Paratroopers
