Hidden is easy and plentiful, highly recommended

The Hidden is easy and simple. The game progresses automatically, which is convenient. Open the training bag whenever you have time, and only claim the bonus reward ads when the speed token appears. I only used gems to buy when the speed token appeared. After growing quickly in the early stages, I occasionally used them up when the purple ticket missions opened. Then, around 6500 trophies, the training playground opens, where you can train the necessary speed. (I watched this ticket ad every day) I played with the Hidden as my goal and cleared it easily (only played when the time quest appeared). Let me know if you have any questions. Have fun and be happy, everyone.
