"The Big Eye Boy table is useful in gauging how repetitive the shoe is. Red entries are a sign of repetition, and blue entries are a sign of a chaotic, "choppy" shoe. It is important to note that in the Big Eye Boy table, blue and red are not associated with Player and Banker wins, as they are on the previous two tables.

The first entry in the Big Eye Boy table is the hand after the first entry in the second column of the Big Road, so that there is enough information to judge if a pattern is developing or not.

If the hand in question causes a new column in the Big Road, then compare the previous two columns in the Big Road. If they are the same in depth, then record a red circle in the Big Eye Boy. If they are not, then record a blue circle.

If the hand in question is the same outcome as the previous hand (skipping ties), then compare the cell to the left of the newly created entry in the Big Road with the cell directly above that one. If these two cells are the same, whether both Player, both Banker, or both blank; then mark a red in the Big Eye Boy. Otherwise, mark a blue. " (text source: wizardofodds.com)
