Lucky Cat Bingo - How to earn Standard Tokens for Challenge?

I can't get it to let me play the single line game.  Nothing happens when I click on the select game

I got the required standard tokens  playing 4 card single line  ... on the first try

This is the second time that you have set a challenge at lucky cat bingo that can only be achieved if you stay glued to the computer 24 hours a day for 6 days, adding up the other daily and weekly challenges, which is physically impossible. I don't know who the smart guy is who set this badge, but mathematics is alien to him. To play 4-card you need 500 tokens, which can only be achieved if you play between 10 and 15 2-card games, where you can only win, for example, 1st place, once out of 10 or 12 games, the rest of the games winning 8th or 9th places, from which you only have 25 or 30 tokens. Very rarely do you get to have 2nd or 3rd place, etc. So, mathematically speaking, with all probabilities, to get to play a 4-card, you have to play at least 60 minutes at 2-card. After all this, there is a possibility of having only 1 bingo at 4-card or none at all. Very rarely you have 2 bingos. This type of challenge of 50 bingos at 4–card game in 6 days is not realistically established. Eliminate the robots, which only make it difficult, not to mention the fact that it gives you a false impression of the game. The robots tick all the numbers, and towards the end they almost always win, which is a big deception. At least, if you don't want to eliminate the robots, leave the player the option to choose whether he wants to play freely or with robots.

I eventuall got it under the "free" single line game.  It took many games.   I can't get enough coins to play any of the 4 or 8 card games.  

I don't understand what you mean about special tokens but I cannot get a bingo all in B's when it isn't a regular format.  Can't get any of the other games because I have the Lucky Cat Bingo open and unable to complete. 

The special event on lucky cat does not give standard tokens. Why put up a lucky cat event and put up a different challenge not possible to play while the event is running. I'm on pause for two days waiting for the event to be over to do a challenge. Is there a way to opt out of the special event?

The daily challenge is impossible to win.  You can't earn the tokens you need they only have 'SPECIAL TOKENS for the duration of the challenge,
