Free memory game software for linux

Guarded Memory Move project gets handy when you have to study buffer overflows and you need to catch them together with a "good" stack image. When a stack overflow has been exploited, the back trace is already gone together with good information about parameters and local variables, that are of vital importance when trying to understand how the attacker is trying to work out the exploit. The GMM library uses dynamic function call interception to catch the most common functions that are used by attackers to exploit stack buffers.
The GMM library uses the LD_PRELOAD capability and offers two services to the user. First of all, it avoids buffer overflow to allow the attacker to execute shell-code on your machine. Second, in case where an exploit is detected, the stack content is saved and a segmentation fault is triggered. The resulting core dump will then have all the necessary information to debug the exploit and fix the software. Internally, the library insert itself between the application and the glibc library and intercept functions that might lead to buffer overflow exploits. Before calling the glibc core function, the GMM layer saves part of the stack frame above the caller to a temporary location in its frame.
It also stores the previous three return addresses in its local storage before calling the glibc core function. When the core function returns, the GMM code samples again the previously recorded return addresses and, if they differ, it restores the previously saved stack frame and issue a segmentation fault. This with a clean stack frame, so that it can be inspected with a debugger. While other solutions exist to detect buffer overflow exploits, like for example StackGuard and StackShield, those differs from GMM in many ways. They live as gcc patches and do require you to rebuild your application to use their functionalities. The good of this approach is that every single function is protected against buffer overflows.
The bad of this solution is that every single function is protected against buffer overflows. That is, performance regression on the whole application, even if this is not really a huge problem when hunting for buffer overflows. Another solution similar to GMM is LibSafe, but it does not save and restore the stack frame by making it unusable for debugging. But lets see how GMM differs from the above listed solutions. First of all, GMM works everywhere there are stack frames and the gcc and glibc duo. That means that it is not limited to i386 only. And now the real reason for the GMM existence.
Enhancements:
- GCCs __builtin_return_address and __builtin_frame_address seems to return garbage instead of NULL at the last frame. This release fixes the problem.

Martian Memory project consists of a simple memory game.
Martian Memory is a simple memory game oriented to kids, featuring the Pachi el marcianos world characters.
The goal of the game is to pick up two identical chips from a board that contains 32. The game contains very nice visual effects, sounds, and very nice music composed by Jonne Valtonen.
Installing
Just do:
./configure
make
make install (as root).
Enhancements:
- Added the -f or --fullscreen switch.
- Changed some chips (removed bloody ones) the game is now "child safe".
- program exits if close window or press [F10].
- if two scores are equal they are ordered by minor time.
- time stops during a combo FX.
- the hiscores screen displays a "press right mouse button to return" sign.

gewee game is a Go-like board game with "next generation" graphics.

This is a game between a human ("player") and a computer ("opponent"). The players objective is to accumulate as many points as possible. When the player wins a game, a point is added to his/her score. When the player loses a game, a point is subtracted from his/her score. The competitor with the most pieces on the board at the end of the game is the winner. A game is finished when a competitor forfeits, or has no valid empty square to place a piece on. The opponent is granted additional moves at the start of a game based on the players score.

Each competitor has a distinct set of pieces of the same shape and color. The competitors take turns placing one piece on an empty square on the board. A piece or group of pieces that has no empty square adjacent to it is removed from the board.

Monkeys Memory is an implementation of the classic game of memory. Classic Game of Memory written in mono where you can play against other people (on the same computer, network game is not implemented jet) or against Computer (there is 2 type of computer player).

There is more level of game from tiny level to very big one.

Memcheck provides the ability to fault on pointer overrun (read or write) or freed pointer deference (read or write), logs double free and realloc of already freed pointers and memory not freed on exit, checks for pointer underrun on free and realloc, optionally reverses the behavior of overrun and underrun, "churns" reallocations to always return a different pointer, and logs pointer overruns instead of faulting.
It has a very small performance impact, with the tradeoff of a large memory footprint. It includes a validation test suite to verify correctness of the library. It is tested on a variety of architectures, including Alpha, ARM, HPPA, PPC, ix86, IA64, rs6000, S390, SPARC, and SPARC64.
It is tested on a variety of platforms, including OSF, FreeBSD, NetBSD, OpenBSD, Linux, HP/UX, Mac OSX, AIX, SCO, and Solaris.
Enhancements:
- Some missing backtraces were fixed.
- An atexit replacement was implemented to catch allocations that are freed by previously installed atexit handlers.
- Deeper backtraces are stored, and internal recursions are handled.

Othello Game is a classic strategy game, also known as Reversi. Its objective is to finish the game with the greater amount of pieces (circles) of the same color.
This version of the Othello game supports the writing of AI plugins in C++ or Python, network games, and interface themes.
Enhancements:
- pkgconfig support was added.
- It is now easier to write AI plugins.
- An installation guide, and a tutorial for writing plugins were incuded.
- It is now possible to disable Python support from the configuration.
- New icons were provided.

Transcend Game project is a retro-style, abstract, collage-building, musical, shooter game.
The graphics are geometrical, and the pace is sometimes frenzied. Two features set Transcend apart from other games.
First, its dynamic graphical engine, which can smoothly morph from one complex shape to another in realtime, produces striking displays.
Combining these dynamic shapes with subtle randomizations ensures that each new play through a level is visually different from the last.
The second novel feature is the musical power-up system.
As you play through a level, you are simultaneously assembling an abstract visual collage and arranging a unique piece of music.
Enhancements:
- Fixed bugs that caused post-explosion fade factors to become negative, which in turn caused boss explosions to linger on some platforms.
- Fixed zoom behavior when strafing.
- Added fade-in when enemies are created to avoid a visual pop-in.
- Added smooth turning when enemies switch targets.
- Changed so that pieces can be picked up while they are moving as a result of enemy fire. This makes pick up less confusing and frustrating.
- Made bullet fade-out smoothly at end of range to avoid visual pop.
- Doubled piece pick-up radius to make picking up pieces easier.
- Fixed jerky piece pick-up and drop.
- Added mini-explosion graphics to indicate when damage is being done to boss. These graphics also change color to indicate the boss health.
