Spectra

From BoardGameGeek:

Spectra is a game for two to four players that employs the same type of logic as the game of Nim. Placing cubes on the board, players hope to end each round with a majority of cubes on as many spaces as possible, thus scoring points. But the order of play and distribution of cubes can have millions of potential combinations. It's a bit of a brain-teaser, but easy enough so that players of any age (above 8) will have fun working out a strategy. The small format makes Spectra a good choice to take on vacation or family outings! -description from the designer
