Help MathPup get across the bridge on each level by correctly filling in the missing pieces in the bridge.
Fill in the missing pieces by dragging and dropping pattern pieces at the bottom of the page onto the question marks found in the bridge. Fill in the bridge with pattern pieces that correctly complete the pattern on the bridge and MathPup will be able to cross the bridge safely once you tap/click "GO".
Note: When the timer reaches zero, MathPup will start out across the bridge on his own. If you are really good with patterns, you can click "GO" and then fill in the missing pieces on the bridge for a higher score. Or choose to play the "Normal" or "Hard" mode.
