Super Concentration

Heartlight is a puzzle video game originally developed by Janusz Pelc for the Atari 8-bit computers in 1990. In 1994, an MS-DOS port (Heartlight PC) was published by Epic MegaGames along with two other games by Janusz Pelc in the Epic Puzzle Pack. The shareware version has 20 levels and the full version (Heartlight Deluxe) has 70 levels. In 2006, Maciej Miąsik, co-author of the MS-DOS version, released it under the Creative Commons CC BY-SA 2.5 license as freeware. The source code became available too. In 2020, a web browser remake was released with updated graphics.

A jigsaw puzzle game for DOS.

Tubes is a shareware color matching puzzle game. The main screen shows a series of overlapping transparent tubes climbing from the bottom and curving at the top towards the center. Colored balls, or elements as the game calls them, travel through these tubes to their exit holes. The objective is to catch the falling spheres with a test tube, moving it sideways underneath the tubes exits with the mouse, keyboard or joystick. The test tube can hold up to five elements. The player has to press a button and drop the elements inside a beaker at the bottom, aligning them vertically, horizontally or diagonally by three or more of the same color. Every level has a number of drops allowed, and when the player fails to catch too many elements the game is over. Besides the elements, special balls also appear randomly inside the tubes that help or hinder the player. The multicolored element acts as a wildcard, and can be matched with any color. The F element removes space inside the test tube. The M element fills the test tube with assorted balls. The C element creates a gray ball that can't be matched. The game comes with two modes. In endurance mode, the goal is to make as many points as possible, by making matches until all the allowed drops are spent. In wave mode, each level (or "wave") has objectives, like making a specific type of match, that must be completed before finishing and moving to the next one.

We have the power to dramatically improve the functioning of our minds. PriMemory™ tests and trains your memory through a series of increasingly difficult sequences of colors and musical tones. Regular use of brain-building exercises can improve your performance and your enjoyment of the game. Make your fun time more productive with a game that challenges your mental abilities and helps improve your memory every time you play. The game's artificial intelligence learns the way you play to build more complex and challenging games as you move through levels. Repetition builds memory. Every trip through the game helps you exercise your mental recall abilities. The more you play, the more you will remember. There's challenge available at every level. Eighty-two percent of humans can't finish the game. Will you be part of the 18% who can? Top Features: PriMemory™ demands more of you every time you play. Each time you play, you get the chance to go back to previous completed levels and challenge yourself all over again. You will never get the same game twice; because of the AI engine, each level adapts and changes each time you play. Relive the excitement by engaging with new variations every time.

Elemental is a color-matching game. The player clicks and drags the mouse cursor over a group of tiles to flip them and change their color. When three or more tiles have matching colors, they are removed from the game. Each stage has one of the classic elements (earth, wind, fire and water) as its theme.

Left-Right: The Mansion is a little game about a boy, Billy, whose dog named Gigi ran away inside a big mansion. He must journey through this mysterious place, where he will have to find and remember the right path in order to find her. Every room will challenge him with a simple choice to make: left or right. Two doors, yet only one will make him go forward; the other one will bring him back to the beginning. Left-Right is a memory game filled with strange creatures and scary bosses who will try to stop Billy from finding his dog. It is a pretty simple and fun 2D game inspired by the old classic games, for which, even after all these years, we still remember the button sequences to avoid the punches or get 30 lives. The human memory is a very fascinating thing, and Left-Right is here to test its limits. Will you be able to help Billy find Gigi? Or will she be trapped forever in this crazy mansion? Enjoy!

Chaotic, voice-controlled memory game. Your rival barged into your home and tampered your elemental grimoire. Monsters have been summoned and the elemental balance has been broken. The elemental laws are rewritten after every fight. Can you adapt to them?

PentaBlox is a single player, shareware implementation of the traditional puzzle Pentominoes. Pentas are shapes made from five connected squares, this means that they all have the same area but a different shape. The player’s task is to fit the shapes into a box. There are twelve shapes in total which must be fitted into a box. The shareware game has just a 6x10 box but the registered game has three other box sizes 5 x 12, 4 x 15, and 3 x 20. Pieces may be rotated and/or flipped in order to position them in the box and there’s an optional grid setting to help with the planning.
