Hexlinx

From the publisher:

Hexlinx is an intriguing game of geometric strategy in which players start each turn with 6 tiles, then score points by trading, switching, and connecting them to build a honeycomb grid of interlocked rings. Each ring must include 6 different color tiles. When all the tiles have been drawn and no player can form any more rings, the game is over. Highest score wins. Uniquely simple yet challenging, this exciting game of logic requires strategic planning (and a little luck) to win. For a variety of gameplay, some optional Rules can be used -- and because there are 2 methods of scoring points (standard and advanced), Hexlinx is FUN for children and adults of all skill levels !
