Cornerstone Essential: Just like the original game of Cornerstone, in Cornerstone Essential players build and climb their towers, working together in teams or in a head to head race to reach the top. Each turn players build by strategically placing blocks, gaining a better vantage point for their Climber or blocking an opponent. Players not only balance the blocks, but also offense with defense. With every move the game gets more exciting as the towers grow taller and more unstable. Can you reach the top before it falls? It will take a little luck, some clever moves, a steady hand and solid foundation to be at the top of this game. Are you up to the challenge? Out of Stock! Unfortunately, we have just run out of stock for Cornerstone Essential and we are unable to take any more orders at this time. We are working to get new games in, but we will not have any until next year. We are sorry for the inconvenience.
