I agree with the post above; it's still gambling because it requires a fee to win something. It isn't earning for free; you are still risking something to be able to earn the pot. There's no big difference in playing digital poker that's based on skill-based games and considered gambling.

Look at this image:



Even if it is player vs. player, it has a fee of 10 sats to 50 sats. The free one is the training ground with a pot of 0 sats. Training ground is supposed to be just your demo.

I tried to play the demo one with a bot, and honestly, it's hard to win on the game. Once I got hit by the enemy bullet, I lost immediately, but when I tried to attack the bot and got hit multiple times, it didn't die, and my bullets are limited to, I guess, 10 shots; it will reload for more than 3 seconds.



The tank retro game is way better to play than this.
