The scores may have 100 million differences just within a minute!? Control your flight to create an equation and earn as many scores as you can! This is a game which you need to control the flight to collect the numbers, 「＋」, 「×」, 「＝」and else to create an equation. Depends on the equation which you have created, you can either earn 0 point or up to million points!! Let me kindly share a tips with you~ If you are aiming for a high score, be careful on the timing to collect the「＝」! ■Remarks: ・If you collected the「－」 or 「÷」, your scores will be deducted according to your equation. ・If you crashed before collecting a 「＝」, your equation will be unfinished. You will not be able to redeem any scores in that case! ・The special ‘Rolling’ skill can avoid the enemies but the use is with limited times.
