Swipe the 6x6 board to move or merge the tiles. The tiles are mixed up elements of a true mathematical expression, and when you arrange them correctly, they will be eliminated. Clear the level by eliminating all the tiles. Obstacles like one-way signs, traps, and stop points add additional challenges to the gameplay. The first 100 levels are available for free! If the free levels aren’t enough of a challenge, you can unlock 50 advanced levels with a small single payment. Advanced Goal: Clear the level within the specified fewest moves. We used a computer algorithm to calculate the fewest moves possible. If you’re not satisfied by just clearing the level, try matching the algorithm. Fewest Moves & Hints: There is a shortest solution to every level, but the solution is locked. If you cannot clear a level, you can unlock the shortest solution one move at a time by tapping the hint icon. After you clear a level, the game will analyze the moves you took. If a move you made matches one of the moves in the shortest solution, the matching move will be unlocked. You can use this information to continue playing the level until you achieve the advanced goal. 1121 includes 100 free levels and 50 extra paid levels. If you achieve all the main and advanced goals in the 100 free levels, the 50 extra levels unlock for free. You can get hints by watching ads or purchasing them.
