Learning the sequence of doubling numbers (powers of two) is a worthwhile pursuit for children of all ages. This game is lots of fun to play, does not require the player to already know the doubling sequence, but presents the numbers in context and in a way that will help the child learn and recognise them. Play the game little and often! Do not spend hours and hours playing but do spend ten minutes every day working to improve your score. Your personal best score is shown at the top right of the screen and this provides a target for you to try and beat. Earn trophies as you achieve the high score tiles. Enjoy playing the game and learning more mathematics as you do. |

It is lovely to have so many different ideas to start a lesson with. Thank you very much and keep up the good work." |

How the scoring works: Every time two tiles merge, the value of the new tile is added to your score. Joining two 2s makes a 4 and earns 4 points, joining two 64s makes a 128 and earns 128 points, and so on. Simply moving tiles without making a merge scores nothing, so the bigger the tiles you create, the faster your score grows. Building a 2048 tile from 2s alone earns about 20,000 points along the way, because every tile that went into it was also scored when it was made. Your best score is saved on this device and shown next to your current score. Trophies are awarded for the largest tile you make (128 for Level 1, doubling for each level after that) and the trophy record shows the score of the game in which you earned it. This game is adapted from code created by Gabriele Cirulli (http://gabrielecirulli.com) based on 1024 by Veewo Studio and conceptually similar to Threes by Asher Vollmer.

"Keep in mind you can achieve numbers higher than 2048 I have actually managed to reach 4096. The language used on the webpage implies the game ends after reaching 2048 and trophies aren't tracked for numbers higher than 2048 and this all irks me."
