They have free satoshis that you can get from the box at the upper portion of the site. Is that not enough to use to test their games? Or you need huge play money to feel the game?
Betfury decreased the daily profit of faucet (free box) from 1800 sats to 720 sats per day. Maybe it's still enough to test some games like Dice, Plinko but I guess it isn't enough for slots. IIRC minimum bets are 0.001 mBTC per line for some slots games.
Yeah but to my understanding, slot games are not their own games, they just host them. Plinko, Dice, Coin Flip, and the one with the rocket raccoon (I forget the name), are their games. In a sense, because there are variations of these games on similar websites. You can play those with the faucet money.
I think it's still nice that they give out as much as they do, especially if you check Bitcoin's price. Obviously, they had to lower it but to be honest I don't know many websites that give 10 sats. per 20 minutes right now.
