What are the yellow stars?

• There is 16 stars on the board. Stars are equal to one point. In order to obtain their points, you must first collect them and then trigger a vortex to collect your star points.

What happens when I collect a star? 

• When you put a letter on a star, you win a star. The star is added to your star counter.
• If you trigger a Vortex, your stars collected are transformed into points. If your opponent triggers the Vortex, you lose your stars.
