In the advanced difficulty level, kids will have to make a twenty or other targeted number to cancel the monsters. 【What Number Monster Covers】 - 10-frame addition - 20-frame addition - 10-frame subtraction - 20-frame subtraction 【Features】 - Colorful & Intuitive game design that lets kids master addition & subtraction through playing. - So easy to play that your kid will get the hang of it within the first round. - A proven method based on preschool curriculum to improve kid's arithmetic proficiencies. - Custom mode available for you to set any target number according to your kid's math skills. - Worldwide ranking enables your kid to gain confidence and become competitive in future STEM courses. 【How to Play】 The goal of the game is to swipe 2 monsters into a position to get a 10 (or other target numbers). This will result in the merger of the monsters. After the merger, the monsters will disappear and new monsters will fall onto the board. Keep repeating this until the board is filled and there is no more space for additional monsters. Begin a math adventure with Number Monster now! 【Contact Us】 Email: support@flickering.ai
