This is a scam website. Do not use it. I did a IQ test in past time, paid $14.90 for one-off game, but then surprised by $129 taken from my account a few days later. I wrote the company asking for refund for the authorised payment, but they returned saying ‘No’ because a subscription (unknown by me) was made when I paid for the game. This is totally a scam. Please do not do anything or enter any payment details on their site.
