The goal of this classic Marble Solitaire strategy game is to remove as many marbles as possible, by "jumping" one marble over another, either horizontally or vertically. 7 levels available.

5 or more left: You need practice!
4 marbles left: Only average
2 or 3 marbles left: Pretty good
1 marble left: You're an Expert!

十字棋:
也叫跳彈珠或者孔明棋。有人說是三國時代孔明所發明的益智棋，失傳後輾轉流傳至日本歐美，成為外國普及的益智遊戲。另一種說法是它真正的名字叫作十字棋，是一個被囚的法國貴族在獄中為了打發時光而發明的，後來在十八世紀末期傳至英國，才漸漸流行至世界各地。遊戲時是將棋子跳過鄰近的棋子到達一個旁邊空著的位置，被跳過的棋子則從棋盤上取掉。跳的路徑可以前、後、左、右，但不可以對角跳，直到剩下的棋子都不可以跳時遊戲便結束。
最後剩下5只棋子是"尚需多加練習"；
剩下4只棋子是"平均水平"；
剩下3隻或者2只棋子是"很好";
剩下1只棋子是"大師"；
最後剩下1只，而且在正中央是"天才"。
