In the game, you need to put the dinosaur eggs back to the nest. Because the eggs are huge, you need to use inertia to roll the eggs back to the nest. Press and hold the screen to drag the L-shaped wood to block or push the eggs. The L-shaped wood can only be used on the left slope. Release the screen and the L-shaped wood will disappear. The game fails if the dinosaur eggs roll out of the screen. The game succeeds after the dinosaur eggs stay in the nest for a period of time. The more eggs you put back, the higher the score. Note that the location of the nest is different in each level.
