EvenBetter is a relaxing mathematics puzzle game. There are no timers, no ads, no fuss.
Rules:
- The player is presented a gameboard of 4 x 4 squares, surrounded by 16 complementary tiles
- The game start with all squares set to 0 and complementary tiles with random numbers from 0 to 9
- Each round, every square on the grid has its value added to the four neighbouring squares/tiles and its value is replaced with the last digit of that sum.
- You have to figure out which square will have an even number on it next round.
- The complementary tiles on the sides are randomly generated every round, so every round is unique.
- The game guarantees that there is always at least one possible choice.
- A round ends when the player makes a choice, values are then computed and a new round starts.
- Selecting a square producing an odd number at the beginning of a round will end the game early.
- There are no time limits.
- The game ends when the player successfully reach the end of level 5 (83 rounds)
Fun facts: At the end of each game, the player is presented with some properties of a number. For example if the player successfully completed 2 rounds, a fact about the number 2 will be given (2 is the only even prime number!). If a player completes all 83 rounds successfully, a bonus fun fact will be unlocked.
School teachers/parents: This game links to external content on MathWorld and a few entries on Wikipedia explaining what some properties of numbers are, such as Mersenne prime, non-trivial values, etc -- knowledge of those topics is not required to play the game.
