Word Letters Sort Puzzle

You can move a letter square onto another letter square only if both have the same letter square and the tube you want to move into has enough space.
Otherwise, the lettered square is rejected.
Tap any tube to move the square with the letter on the tube to another tube.
Try to separate the letters in the tubes until all the squares of the same letter remain in the same tube.
Collect all squares with the same letter in one tube.
You can retrace your steps one by one using the back button.
You cannot step back in the tube you closed.
With each completed tube, the letter of the hidden word is unlocked.
If all the lettered squares are lined up in the correct tubes, the entire hidden word becomes visible. The level is completed successfully.
It's a challenging puzzle, try not to get stuck but don't worry, complete the letter sorting game.
If you get stuck you can restart the level as many times as you want.
