On a small field of three by three cells, you will first stir Roman numbers in the game Math Merge, then polygons, Mayan numbers, fractions and cardinals will be added to them. All of the above options will appear at the bottom as you progress through the levels. You can add each item only if you have enough coins. By connecting two identical objects, you get a new, doubled value. The higher the value, the more cash receipts you will receive. If an object, number or shape bothers you, you can remove it by clicking on the basket at the very bottom of the field in Math Merge.
