In addition to what Abhi said above.
The Wiki maps & videos are extremely helpful.... including for the things such as hidden gifts/bonuses.
How many tiles/bricks are left to clear the game scene/mine?
Sometimes with the Last Tile Finder...you need to try activating in different game scenes or different places for it to get a clear path.
Screenshots & the more detailed information you can provide makes it much easier for other players to be able to assist you.
