      • Each time you finish the game, you have the option to save your final score on the leaderboard.
    • Basic rules
      • Form full equations from the operators and numbers onscreen to remove them from the stack.
        • You can make equations which are as few as 5 characters or as many as 9.
          • Each equation must have at least the minimum aspects & in this order
            • number
            • operator
            • number
            • equal
            • number
          • Your maximum limit is a maximum of 9 numbers and operators, including the end result and the equal sign.
            • The longer and more complex your equation, the higher your score will be.
            • You can use single digit, two digit, or three digit numbers in your equations.
            • If you use shorter numbers you can include multiple arithmetic operators before you get to the solution of the equation.
        • You can only use free tiles to form an equation.
          • Free tiles comprise tiles with no tile on at least one side (left or right).
          • The game helpfully highlights the tiles that are open in a brighter hue, with other tiles in a darker hue.
        • The equation formed by the tiles must be correctly formatted.
        • The answer must be correct.
        • Select OK to lock in your answer. If it is correct the tiles will be removed from the board & you can start making your next equation.
      • Clear all the tiles in the stack to win the level, or clear tiles until you either run out of number operators or equal signs & you will move on to the next level.
      • Use wild card tiles (in both number and operator flavors) to substitute for a specific value you don’t have available.
        • Number wild cards can stand in for any number between 0 and 9.
        • Operator cards can stand in for any of the 4 basic arithmetic functions (addition, subtraction, multiplication & division) or the equal sign.
        • In most cases, they will form any conceivably correct equation using any of the parts you have. Sometimes, though, you cannot form a valid equation with the items in your hand.
    • Scoring and hints
      • Points
        • The length of your equation determines your score. Longer equations net you more points.
        • The minimum amount of points you get for most valid answers is 18, though on rare cases it can be as low as 4.
        • If you use all 9 slots and multiply or divide multiple times it is easy to score many hundreds per answer.
      • Hints and reshuffles
        • If you’re ever stumped, take a hint or reshuffle the board.
          • After you select the hint button, the game automatically highlights a valid equation.
          • Reshuffling the stack changes the position of every remaining tile. This will allow you to make new equations if the previous arrangement didn’t yield anything good.
          • If you have enough tiles to make another equation but can not given the current tile positions the game will automatically shuffle the tiles for you. Automated shuffles do not cost you points.
        • Hints and reshuffles cost 500 points, so use them sparingly.
          • Doing so too early in the game will give you a negative score if you don’t have enough points.
          • We recommend rarely using those features & instead saving the easiest to play tiles for the end of the game.
    • Tile play order
      • Each board has tiles in the middle and two isolated columns on the sides. In general it is best to take tiles from the center area and try to save the side tiles as much as you can for later in the level to keep your options open & work off many of the tiles in the center.
      • If you see multiple equal signs next to each other in the center portion of the field try to use at least one of them early to prevent them from blocking plays later on.
      • Try to save the wildcard tiles and easy to use numerical tiles for later in the game. You can add 0 to any number, subtract 0 from any number, or multiple or divide any number by 1 to get itself as the solution, making those numbers easy to play to use up other tiles.
  • Target Audience
    • The game is suited for players who like Mahjong Solitaire games or math logic puzzles.
    • The game has no adult themed content.
