A resident of Mexicali, Baja California, northern Mexico, recently found an envelope with '○△□' printed on it in a crack in the door.
Inside the envelope that looked like an invitation from the Netflix series 'Squid Game', there was a notice telling you to pay your unpaid water bill.
Mexican media reported on the 14th (local time), Mexican media reported on the 14th (local time) that the Mexican public service authority, which sent the notice, explained that it was "a strategy to use the popularity of the series to attract users' attention in a friendly way."
It cost only 100 pesos (about 5,800 won) to print about 1,000 envelopes with circles, triangles, and squares.
Authorities expect to collect 1 million pesos (about 58 million won) in unpaid fees with small investments and novel ideas.
As the 'squid game' was very popular in Central and South America, including Mexico, marketing using it also appeared in various places.
Mexican professional wrestling 'Lucha Libre' also incorporates 'squid game'.
IWRG, one of the Lucha Libre organizations, used the image of 'Squid Game' on the poster for the game on the 17th.
It's not a tug-of-war or dalgona lottery, it's a lucha libre game as usual, but as in the drama, the prize money is accumulated in each round and the final winner takes it, sports media Marca reported.
If the players agree, the match may be stopped and the prize money shared.
In addition, an image from the 'squid game' appeared on the front page of the El Salvador newspaper, the home team, ahead of the 2022 Qatar World Cup qualifiers between Mexico and El Salvador the day before.
The sports magazine El Graffico wrote on the front page of an image of giant dolls and facilitators who appeared in the game 'Mugunghwa Blooms', standing in blue clothes, the color of the El Salvador national team uniform, and wrote, "I'm waiting."
