I don't even understand what the use of the spin is, I have claimed 100 spins, but it seems like this is just a spin like a mini app airdrop task, and there is no gambling context, whether you can gamble on ton station or not I don't know, because this thread was created on the gambling board so I focused on it being for gambling games, in fact it's not like that
This is not a slot. TonStation is a kind of aggregator of telegram mini-applications, among which there are, among others, mini-applications for playing poker and for various bets (similar to a small Polymarket). At the same time, on TonStation you participate in contests with large prize pools (currently there are two of them: Season 3 and the beach party).
Raising the competition leaderboard depends, among other things, on the activity in the applications aggregated here. Spins allow you to win points and tickets to raise the leaderboard, as well as tokens (which can be sold or sent to staking), or TON. You can also win keys to buy loot boxes and spins. Loot boxes may contain Telegram gifts and other prizes.
In fact, TonStation contests are like a lottery, where you earn yourself a better lottery ticket by your activity (which does not exclude the element of unexpected luck). You receive your winnings after the end of the competition or the season, when the prize pool is divided among the participants depending on their place in the leaderboard.
I tried to explain as much as I could in detail; I hope this will help you figure it out.
