Numberix

Numberix is simple to describe: connect the numbers in order and cover the whole grid with one line. Start at 1 and drag. The line has to reach 2, then 3, then every number in sequence, and by the time it touches the last one, every open square on the board must be filled. No skipping a number, no crossing your own line, no empty squares left over. There is exactly one route that does all three. Finding it is the game. How to Play - Drag from the 1 to begin the line. - Move up, down, left or right — never diagonally. - Pass through the numbers in ascending order. Touching one out of sequence is not allowed. - Every open square must be covered when the line reaches the final number. - Swipe back along the line to undo as far as you want and try another route. On the Board - Walls sit between squares and block the line from crossing that edge - Rocks fill a square entirely and the line must route around them - Larger grids hold more numbers and more ways to trap yourself Features - Reverse as far as you like — no penalty for exploring a wrong route - One-finger drag controls, no timer and no move limit Start at the 1, keep an eye on the squares you are leaving behind, and find the route that reaches the last number with nothing left over.
