The active cube follows the player’s finger around the board and locks in place when touched.  
   
Lines of three or more matching cubes are released using either a two-finger touch or a double touch. The two-finger release is quicker – just touch any two points on a line at once.  
   
Multi-colored cubes can be rolled in specific patterns which always bring certain faces uppermost. Learning these moves allows higher scores to be achieved.  
   
   
 
   
   
 
   
   
The score for releasing a single line of matching cubes ranges from 70 for a three-cube line [10+20+40] to 2550 for an eight-cube line [10+20+40+80+160+320+640+1280].  
   
Scores for lines released within three seconds of each other are multiplied. Scores can be further increased by releasing consecutive lines more quickly. On a well organized board many lines can be released in a multiplied chain.  
   
Whilst scores in excess of 300,000 have been recorded, random cube distribution and a scoring system finely tuned to individual skill mean that the maximum possible score is unknown.  
   
   
 
   
   
 
   
   
Creating the maximum number of lines that can be released at one time is usually best achieved by building out from corners or by forming columns from a particular edge. .  
   
Achieving the correct balance between eight-cube lines and those of other lengths is critical in achieving the highest scores.  
   
Enhanced awareness of space, color and time is experienced during prolonged periods of play and is essential to mastery of i3.
