Gheos

The players are gods at the dawn of time, creating earth's landscape and inhabiting it with people. They can command the creation and destruction of continents and the rise and fall of civilizations.

As gods, players seek to gain followers among the civilizations. They offer those followers luxuries, and oversee the building of pyramids and temples on their continents. In the end, the god with the most loyal, wealthy, and powerful followers will become ruler of gods, and wins the game...

Play involves placing triangular tiles to form islands, coastlines and continents. Players can also replace tiles to reform the topography of the planet.

Each civilization is represented by a color, and once a civilization is “born” a player can gain worshipers in that civilization, which in turn may score points for that player in various ways.

The placement or replacement of tiles may result in civilizations migrating, or going to war with other civilizations. These things are resolved by the various icons on the tiles.

The game is fairly simple, but offers quite a lot of tactical possibilities.

DVONN

DVONN is played on an elongated hexagonal board, with 23 white, 23 black and 3 red DVONN-pieces. In the beginning the board is empty. The players place the pieces on empty spaces of the board, without restrictions. They place the DVONN-pieces first and their own pieces next. Then they start stacking pieces on top of each other. A single piece may be moved 1 space in any direction, a stack of two pieces may be moved two spaces, etc. A stack must always be moved as a whole and a move must always end on top of another piece or stack. If pieces or stacks lose contact with the DVONN-pieces, they must be removed from the board. The game ends when no more moves can be made. The players put the stacks they control on top of each other and the one with the highest stack is the winner.

This game is part of project GIPF.

Blokus

Blokus (officially pronounced "Block us") is an abstract strategy game with transparent, Tetris-shaped, colored pieces that players are trying to play onto the board. The only caveat to placing a piece is that it may not lie adjacent to your other pieces, but instead must be placed touching at least one corner of your pieces already on the board.

There is a solitaire variation where one player tries to get rid of all the pieces in a single sitting.

Components:
Blokus Game Board (400 squares)
84 game pieces (four 21-piece sets of red, green, blue, and yellow)
Each color inlcudes:

1 one-square piece
1 piece with 2 squares
2 pieces with 3 squares
5 pieces with 4 squares
12 pieces with 5 squares

Goal of the Game:

Each player has to fit as many of his/her 21 pieces on the board as possible.

How to Play:
1. Each player chooses a color and places that set of 21 pieces in front of his/her side of the board. The order of play is as follows: blue, yellow, red, and then green.

2. The first player (blue) places any of his/her pieces in a corner square. Play proceeds clockwise around the board (yellow, red, and green), each player putting their first piece down in one of the corner squares.

3. Play continues as each player lays down one piece during a turn.

Each new piece must touch at least one other piece of the same color, but only at the corners.

No flat edges of same color pieces can touch.

There are no restrictions on how pieces of different colors can touch one another.

4. Whenever a player is unable to place one of his/her remaining pieces on the board, that player must pass his/her turn.

End of Game:
The game ends when all players are blocked from laying down any more of their pieces. This also includes any players who may have placed all of their pieces on the board. Scores are tallied, and the player with the highest score is the winner.

Scoring:
Each player counts the number of unit squares in his/her remaining pieces (1 unit square = -1 point).

A player earns +15 points if all his/her pieces have been placed on the board plus 5 additional bonus points if the last piece placed on the board was the smallest piece (one square).

There are unauthorized versions of the game published under various names, including The Strategy Game, Tetris, Blokád (unofficial Hungarian version with cardboard pieces) and The Family Chess Game.

Basari

Several games use the simultaneous action selection mechanism, but this is perhaps one of the best.

Basari is a game of gem merchants competing in a marketplace, racing, collecting, trading, and predicting what the other merchants will do.

To start the game, players receive 12 gemstones (3 each of 4 colors).
Each turn there will be a movement phase and an action phase:

For movement, everyone simultaneously rolls their die and moves their markers around a track.

They then choose one of three different actions to perform. The actions are:
- to take a variety of gems from a market stall,
- to immediately score from between 4 and 7 points, or
- to roll and move again and also collect points.

The action cards are revealed simultaneously. If only 1 player chose a particular action, they simply perform that action. If 2 players chose the same action, they barter back and forth with gemstones. One player will eventually accept the other's offer of gems, and the other will take the action. If 3 or 4 players all chose the same action card, that action is cancelled. Note that in 4-player games, there will always be a conflict in choice of 3 actions, so much more negotiating goes on.

A new turn begins with everyone rolling their die, moving, then choosing and revealing their action cards. When any merchant piece completes a lap around the board, the round ends and bonus points are awarded based on who has the majority in each gem color and who has completed a lap. After three rounds, the game is over and the highest score wins.

Qwirkle

This abstract game consists of 108 wooden blocks with six different shapes in six different colors. There is no board, players simply use an available flat surface.

Players begin the game with 6 blocks. The start player places blocks of a single matching attribute (color or shape but not both) on the table. Thereafter, a player adds blocks adjacent to at least one previously played block. The blocks must all be played in a line and match, without duplicates, either the color or shape of the previous block.

Players score one point for each block played plus all blocks adjacent. It is possible for a block to score in more than one direction. If a player completes a line containing all 6 shapes or colors, an additional 6 points are scored. The player then refills his hand to 6 blocks.

The game ends when the draw bag is depleted and one player plays all of his remaining blocks, earning a 6 point bonus. The player with the high score wins.
