Science Ninjas Valence Card Game
Check out your hand; find a set of Valence numbers that add up to 0; coordinate the color of each element; create a molecule! In Valence, it's that simple - and players find themselves learning quite a bit about chemistry at the same time they're having fun!
Can ninjas with super powers in a game format teach us the basics of chemistry? You bet! This well-designed and visually appealing game uses element and molecule cards to show what combines with what. Besides showing one of the ninjas in an action pose, element cards show name, symbol, atomic weight, color box corresponding to section of the periodic table, electron orbital pattern and a +/- number for giving or taking valence electrons to combine with other elements. Molecule cards are two-sided. One side displays graphics of the ninjas in action, along with color boxes that correspond to the type of elements needed to make the molecule, a symbol guide for possible actions, directions for use in the game, and point value. The back side shows name, chemical formula(s), elements and number of each required to make the molecule as well as a brief description of properties and where you might find them. Symbol guide tells you whether the molecule is stable, a reactor, vulnerable to reaction, or blocks a reaction.
Game play involves various ways of collecting element cards and building as many molecules as you can. Reactions can involve your molecule stash or that of an opponent, but reactions can be blocked, so players need to stay vigilant during other players' turns. More complex molecules score higher points, but various strategies can lead to victory. For 2-4 players, with games lasting 15 - 25 minutes.
