Earthquake is a rummy-style card game using a scoring system that multiplies off of opponents' played suits. While your depth of choices for optimal scoring may seem limited, 2010the key is in the bluff. Your best strategy may lie in holding back until an opponent feels secure enough to lay a few cards allowing you to capitalize on their play. Earthquake seems to embrace the upper-management mentality of "profit by compounding the efforts of others" to great psychological effect. Nothing angers a gamer like helping an opponent score or worse, giving them the victory all-together! This is a great 'tweener game (played between larger, meatier games) or after a long night of gaming, when you lack the head for something with a bit more depth. Earthquake is also an excellent choice when gaming with young children as there is little reading, simple rules and the cards that do have writing are incredibly concise and easily memorized. The only aspect that may give young gamers difficulty is the basic multiplication in the scoring, though the scoring concept is easily grasped and can be assisted in by an older player. This is one of my favorite quickies... a constant battle of one-upmanship or X-upmanship (with the multiplying score mechanism). If you can get your hands on a copy (and it will be a challenge) this is a must for a lite filler.
