Hi Nakazawa, thanks for the report. Could you provide more details to help us? How did you "claimed twice in a row"? You tapped the Claim button once and 2x arena tickets flied up and 2x 500 coins added to your total balance? Or after you claimed it, several seconds later the Claim button could be tapped again?
Thanks for the report. While this may appear weird, but it's expected as number of slots before reaching the big wheel changes daily between 4 and 5 randomly every day, and what likely happened is when you claim the bonus around the daily refresh time, the total slot number changed from 5 to 4, enabling the big wheel spin earlier than you though it would happen.
