Playing with cards is more fun but breaking records is not much easier as we think. The surrounding should be Lean the cards in a little toward each other for support. That means there should be a tiny gap between the bottom edges of cards next to each other. Then add cards, forming more T shapes, to make a grid. Next, lay cards flat on top as a roof, then add a second row. It is easy to share this tips but here A 15-year-old boy, Arnav Dhaka, holds the Guinness World Record for designing huge structured castle which made of decks of cards used for gambling.
He is from Kolkata, West Bengal and has used 1 lakh 43 thousand cards. This has also created a record of the world’s largest building design made with blocks of cards. Arnav Dhaka has built this grand structure on the model of 4 famous buildings in Kolkata – Writer’s Building, Shaheed Minar, Salt Lake Stadium and St. Paul’s Church.
For this, he visited all the 4 famous buildings in person and noted the construction details. Based on that, he has built a structure by stacking cards one after the other vertically, horizontally, crosswise and lengthwise.
He handles the decks carefully as even one card slips in the deck and the whole effort is wasted. For about 41 days, he has been patiently stacking decks of cards and creating realistic structures. The structure is 12.21 meters long, 3.47 meters high and 5.08 meters wide.
In this Shaheed Minar has a steep height, so Arnav Takah had a lot of trouble to build it on blocks. Initially, the blocks have collapsed when raised a few feet. He has worked hard to fix it and prevent other structures from collapsing. 
That’s why he says it took 41 days to build the entire structure. He has undertaken this work in between studies. Another reason for the longer days, he says, is that both have to be handled in balance.
Arnav Taka started making small designs by stacking decks of cards at the age of 8. The Corona period has increased the interest in creating grandiose designs. That is the basis for the creation of a large-scale card structure on a global scale.
The Guinness website has released a video of Arnav Dhaka stacking cards to form structures.
