I used to play a lot when I was younger.
Nowadays I enjoy playing once or twice game a day, so why not earning some tokens while playing?
The following list is for casual gaming, for a more competitive approach I think there are some tournaments that rewards bitcoin on Lychess.
Dchess
Here's the whitepaper: Dchess;
You can earn King tokens winning matches, it's an incentive even if the value is really low.
There are some burnings mechanics and you can spend the token in the shop.
The price of what is being sold is so high you would probably play for years before being able to buy something.
Here's examples of chess pieces and boards prices.
There are a lot of interesting mechanics (staking boards to farm kings, scholarship), the site is updated constantly.
The withdraw of tokens is set at 500.
sMiles
sMiles is a moving to earn app.
In the offers wall you can play chess puzzles and matches to earn satoshi.
The chess puzzles are not very difficult and you'll earn 1 satoshi every puzzle solved.
It's a decent training for an amateur player when you wait in line to buy shit you don't need.
Chess Universe
I can't use this app, my womplay account doesn't recognize it.
You can earn wombucks and eos nfts for dungeon master.
The graphic is childish, but it offers problems, online playing. It's a complete app for playing chess and train yourself.
WEIRD APPS
Metachess
I don't understand how the site works.
It should P2E, I've registered few months ago, it doesn't seem being developed anymore.
