All levels are solvable. Solvability is thoroughly tested by two independently written robot solvers (exhaustive search programs) before every release to guarantee that every single level has a solution.
If you look at the top of the word grid while playing a puzzle, you will see a count of people in the world who have already solved this puzzle.
The theme of WordBrain works on the following mechanics:
=> Solve the words in the order they appear under the grid.
=> Pay extra attention to which letters you choose to include in the words when there is more than one to choose from. This is very important! If you pick the wrong letter you might be in a dead-end, while the right one will make it possible to swipe the next word(s)!
If we put it another way, there is often more than one way to swipe a word. One of those swipes might make it possible to solve the next word and the word after that and so on. At the same time, an incorrect swipe of that same word might lead to problems and eventually you will be unable to swipe words as you play ahead. So, as the game progresses ahead and you reach difficult levels, you would need to try to foresee this and plan ahead to do good swipes.
So, as long as you:
1) Find the right words
2) Swipe them correctly,
you can get through a puzzle with ease.
Please give this puzzle another try! We are sure you will solve it! :)
