How to play

• Every box contains a value, from 0 to 3
• Each time you discover a new number, your score gets multiplied by it
• Game ends if you click on 0 or uncover all 2s/3s. Quitting game makes you keep your current score but counts as loss
• If you win the game by discovering all 2 and 3, you get to the next level. If you fail too many times, you can fall to lower levels.
• Each level is more difficult than the previous, but you also get more points. There is a maximum of 8 levels.
• Numbers at the end shows the sum of all numbers in the row/column (green value), and how much zeroes there are (red value).
• Just click on a box to show it. If you want to mark the box like a draft, right click to open the memo or hover on the box and type the number.
