BoxWorld is a puzzle game where the player has to place boxes over special places in order to gain energy to teleport to the next level. The boxes can only be pushed, not pulled, thus requiring ordering of the boxes with caution. If the boxes are put into positions that prevent further movement, the player can start the level over, but loses a life by doing so. There are no time limits, so the player can relax and think before acting. The game features nice graphics, enjoyable music, and 525 increasingly difficult levels. The player must come up with more complex strategies on the later levels, with many more pushes and special tricks in order to place the boxes in corners or long corridors. Sometimes most of the boxes are already placed in the appropriate area, but the player has to replace all the boxes just to be able to move another box and arrange it where it belongs.
Phlipple is a unique puzzle game. The goal of every level is to reduce a 3D shape to a single square. Elimination of squares is done by flipping edges around just like in a cardboard box. It starts off relatively easy to teach the basics, and provides hours of brain tickling fun. It's a great way to train memory as well as orientation in 3D.
Klest-crossword is a program for creating crossword puzzles. It comes with more than 1000 puzzles and dictionaries of 31000 Russian words and 41000 English words.

Mazeman is an original puzzle game, somewhat like "chip's challenge", except that it can generate new randomized puzzles from a carefully-balanced array of elements. The objective is to find the gems amongst the other dynamic maze elements. A very terse and powerful scripting language and an integrated script debugger enable users to generate their own maze designs. Scripts allow new players to acquire skills gently and provide diabolical puzzles for the expert.
RufasGate is a combination of the Portal and Sokoban games. Using stargate terminology, there are Zero Point Modules (ZPMs) that power the portal guns, which in turn create the two ends of a temporary and short range wormhole, a shortcut through space-time, that allows obstacles to be bypassed. In order to empower the portal guns, all cylindrical ZPMs must be bumped onto their base receptacles. There are currently only four levels, and no way to save a game. RufasGate is also a testbed for learning/illustrating various modern OpenGL techniques including cubemaps, water reflections, sound, and glsl shader capabilities. For anyone planning to use SDL2, it illustrates key-mapping, to get improved keyboard responsiveness from SDL. It supports laptops and high DPI Mac Retina displays.
RufasCube is a slider puzzle where there is a 3x3x3 arrangement of cubelets with the center one missing, allows sliding permutations. After a randomization, the goal is to restore the cube to its original configuration based on color and alphabetic hints. It is challenging, but not as difficult as a Rubik's cube. Here, diligence pays off. Also, incremental solution is possible - you can unscramble one slice at a time. When you finish, you can see the entire English alphabet appear on the 26 cubelets. It supports laptops and Mac Retina displays.
