Swap adjacent gems to make rows or columns of 3 or more matching colors. Drag a gem onto its neighbor, or click one gem then click an adjacent gem to swap.
After a match clears, gems fall and new ones fill in from the top. If those create new matches, they chain automatically for bonus points.
Swap two special gems together for powerful combos. Bomb+Bomb makes a bigger explosion. Line+Line clears a full cross. Rainbow+Bomb explodes every gem of that color.
Each gem cleared is worth 10 points. Longer matches and special gems add bonuses. Cascading chains multiply your score.
The Avg/Move display tracks your average points per move. Use the slider to change the number of gem colors.
