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.
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.
Rummy Pong is a mouse-driven browser game that features the ability for the player to score against the computer (and vice-versa) with color and number sequences, similar to the ones found in the card game Rummy. The player with the highest score is the winner after a certain point difference between scores is reached. Good reflexes and looking ahead always help, but the speed of the ball is adjustable via the keyboard.
Ruzzle Solver PRO is an offline solver (aka cheater) for Ruzzle puzzles. It aims to be usable, fast, and easy to extend and improve for both users and developers thanks to a sensible and modular design. It allows you to add, replace, or update the dictionaries and the score tables, thus supporting an arbitrary number of languages.
