Build your egg tower and pass the barriers, but beware! Keep it smooth, on the right timing and the right level. Touch the grass 3 times with perfect landing to reach the Square Bird Fever mode.
Click to build square eggs which make a tower to keep you from hitting objects.
If you make just the right amount of eggs to avoid the obstacle, you get a perfect landing. Get currency to buy new skins for your bird and levels! Fever mode is activated when you make three perfect landings which makes Square Bird shoot blocks ahead to destroy everything in your path. This shooting makes it much easier to get through the level. Get fever mode as often as possible to score big points.
