Gameplay levels

There can be levels where if user is able to solve one grid, they will advance on to other level. User will keep advancing levels until they lose. When game ends, the total score they made so far will be their final score.

Just a suggestion, you can divide game into various options like:

1. Time-limit : wherein the user will play until a timer ends and will receive a bonus time depending on the word size. (kind of like deathmatch where there is no end)
2. Campaign : wherein suppose for each difficulty level there be a fixed number of levels and with each level time will increase, high score for each level can be score so that there will be some competition in users.
3. Trial : which I think is currently there.
