Free strategy game software for linux

Gridlock is a collection of 30 grid-based strategy board games for Linux, including Ataxx, Reversi, Checkers, Gomoku, Connect Four, and more. They are individually described in the "Games" section.

After launching the application, the game window will appear. Select the game you want to play from the "Game" popup menu in the upper right. Some games have different variations (board size, layout, etc); when one of those games are selected a "Variations" popup menu will appear from which you can select a variation.

The bottom right displays the color and status of the two players. Each players color is shown by a circle; the player whose turn it is has a filled circle. For games in which players have a score, the scores are shown next to the player labels. Popup windows underneath each players label allow you to specify whether each player is human or computer-controlled, and the difficulty of computer players. (Note that "Hard" and "Very Hard" computer opponents may take several seconds to make each move).

The rest of the window contains the game board. To make a move, click on the cell where you wish to place a piece. Some games require that you move from one cell to another; to do this first click on the cell you wish to move from, then click on the cell you wish to move to. (In some games such as Checkers you may be able to make a move containing several jumps; to do this click on each cell you wish to jump to in sequence).

For all games, cells that are legal moves will become highlighted when you move the mouse over them. A black dot indicates the position of the last move. If you are unable to make a move, you can pass by clicking the "Pass" button on the right. The "Restart" button will restart the game, requiring confirmation if a game is in progress.

The "Preferences..." menu item in the main Gridlock menu opens the Preferences window, which allows you to change the appearance of the game pieces, and to enable or disable the animation when they are captured. Game pieces can either be bitmap images chosen from the popup menus, or solid colors chosen from the color wells.

Games can be saved and restored using the "Save" and "Open" commands in the Game menu. Games are saved with their full move history, so you can save a game after it is finished, open it later, and undo moves back to the beginning.

The Edit menu contains Undo and Redo commands. Selecting Undo will back the game up to the last time it was a human players turn. There is no limit to how many moves can be undone. Selecting Redo will redo a move that was previously undone, but only if no new moves were made after the undo.

The Window menu contains commands to toggle the display of network and statistics drawers. The network drawer is described below and is primarily used to chat with your opponent during a network game. The statistics drawer shows a table listing all the moves that have been made in the current game, and information on the analysis performed during the last move made by a computer player.

Tenes Empanadas Graciela (TEG) is a turn-based strategy game based on Risk.

Tenes Empanadas Graciela (TEG) is a turn-based strategy game, a clone of "Plan Tactico y Estrategico de la Guerra" based on Risk.

Ophiuchus is a multiplayer strategy game in a similar vein as the Master of Orion series.
Ophiuchus will go through many phases where it is a completely playable game and it comes with further features added on with each major release.
The reason for this is that it is quite impossible for me to create a fully-featured game in one go. Doing it in steps allows me to re-check the game for gameplay quite often. (This also means I get to play it a lot, which serves to keep me interested.)
I aim to eventually create a game of rather large proportions, but this may well take some time. As such, I am concentrating on the gameplay of the game first, on the assumption that while graphics improve and change, gameplay stays eternal.
The game map is a rectangular board of tiles. A tile may contain a star. Each star is orbited by a single inhabitable planet. Each player starts out inhabiting a single planet, and owning 10 units of money.
Each planet a player owns adds 1 unit of money to their treasury per turn. You may build spaceships at your colonies, which cost 4 units of money, and take 1 turn to construct. Spaceships move across the map at a rate of 1 square per turn.
If a fleet encounters an uninhabited planet, it will automatically colonise the planet. If you encounter a planet owned by another player, you can attack and invade it. Combat works on the simple principle of winner-takes-all.
Whichever side has the larger fleet destroys the other side. If you retreat from combat, that is, if you order your fleet to leave a system while another player orders their fleet to attack yours, you lose a third of your ships.
You win the game by invading all colonies held by all other players.
Enhancements:
- When multiple players arrive at the same uncolonized system at the same time, none of them can colonize the planet now.
- Previously, the player with the lowest ID got the planet, leading to an advantage to players with lower IDs.
- This was a problem especially in single player mode, when it gave a great advantage to the player over the computer.
- Attack commands now always give feedback.

FreeOrion is a turn-based game of epic space strategy game witch is inspired by Master of Orion.

It builds on the classic 4X model by incorporating the nation-building elements of games such as Europa Universalis 2 and a versatile tactical combat engine.

While its modular design allows for a significant degree of customization of the game engine and the story elements by the community, the development team is dedicated to the construction of a living, breathing universe in a grand campaign model.

World Domination is a Real Time Strategy game inspired by the board game Axis and Allies utilizing the Stratagus engine.
World Domination will emphasize strategy and not "see who can build the most units the fastest." Resources are not gathered like in other RTSs, rather they are distributed after a fixed interval of time based on how much land a player occupies.
Enhancements:
- Added support for AI.
- Fixed may bugs and desyncs so you should be able to finish a network game without it crashing.
- New Graphics.
- Some new Maps

GQuiz project is a GTK+ based tool for helping with memorization.

GQuiz is a generic question/answer drilling program.

You provide a program that displays the question and answer, given as a single filename on the command line, and gquiz randomizes, prevents immediate repetition, and temporarily eliminates questions youve answered correctly "enough" times in a row.

The author uses GQuiz with cgoban to study go, the Asian strategy game, but it could just as well be used to memorize States and their Capitals, or foreign language vocabulary, etc.
