Fraction Order Trail — Rules, Examples and Help
Choose a path of neighboring fraction cards in strictly increasing mathematical order.
How to play Fraction Order Trail
The grid contains fraction tiles. Your route starts on the tile marked Start and must end on the tile marked Finish. Tap tiles in the order you want to travel. Every next tile must be directly above, below, left or right of the previous tile. Diagonal jumps are not allowed. Values must increase strictly at every step, and the route must use exactly the requested number of tiles without visiting a tile more than once.
Compare fractions without guessing
When two fractions have different denominators, compare them by cross multiplication. To check whether 3/8 is smaller than 2/5, multiply 3 × 5 = 15 and 2 × 8 = 16. Since 15 is smaller than 16, 3/8 comes first. You can also convert fractions to a shared denominator, 15/40 and 16/40, to see the same order. The game validates each step using exact multiplication of integers.
Planning a connected route
The smallest number in the grid is not necessarily useful if you cannot reach the Finish tile from it. First identify Start and Finish, then look for an increasing chain that respects neighboring squares. Avoid jumping directly between tiles merely because the numbers are sorted. A correct numerical sequence is not enough when its steps are not connected. On a 4 × 4 Hard board, plan a few moves ahead before committing to a tile.
Using route controls
A selected tile displays its position in the route. Tap the last selected tile again to remove it. Undo restores the previous route and marks the round as assisted, while Hint can show a step in one valid path. Easy games use a shorter route, and Normal and Hard require longer routes. Daily puzzles remain repeatable on the same UTC day, while Practice creates fresh boards.
Common questions
Can two different routes be correct? Yes. A route that uses the required number of distinct tiles and obeys all the rules passes even if it differs from the sample path. Can I travel diagonally? No. Can a tile have the same value as the one before it? No, the order must be strictly increasing. Do I need to use every grid tile? Only the number stated above the board.
