The short answer
There is no route from a Lucky Time Slots balance to money. The game holds no gambling licence because none is required where nothing of monetary value is at stake, there is no cash-out screen, and Coins cannot be transferred to another player. Winning a community jackpot is a real event inside the game and worth nothing outside it.
Why the machines look so familiar
This is the main source of confusion here, and it is a reasonable one. The library carries officially licensed content from real slot manufacturers, including Konami and Ainsworth, so machines you have played on a casino floor appear here under the same names and with the same artwork. The licence covers the look and the mechanics, not the payouts: the cabinet in a casino pays money because the casino is licensed to take bets, and the copy in this app pays Coins because it is not.
Are the odds the same as the real machines?
No, and there is no reason to assume they would be. Regulated machines publish audited return-to-player figures because gaming commissions require it. A social casino has no such obligation, so the maths can be tuned for engagement instead, and the developer does not publish it. That is worth knowing before treating time in this app as practice for anything, and it is why the store listing carries the standard warning that success here does not imply future success at real-money gambling.
What the jackpots actually pay
The Lucky Time Jackpot is a community progressive that must be won within a window once it activates, and the Supreme Jackpot sits behind the High Rollers Lounge at level 77 and above. Both pay large Coin amounts, which matter inside the game: they unlock higher-stakes play and leaderboard positions. Neither converts to anything outside it, and no amount of jackpot winning changes that.

Is it legitimate?
Yes, as a game. It has been running since the mid 2010s with a library past 150 machines and regular additions, it carries genuine manufacturer licences, and it was acquired by Octro in December 2023. It does what its listing says. What it does not do, and does not claim to do, is pay out.
The free way to play it
Spend nothing, collect the hourly bonus, use the Bonus Multiplier Machine before the bonuses it multiplies, let the Boomerang Bonus turn yesterday's spins into today's balance, enter the tournaments, and take the Coin links. That last one is what this page collects, newest first, so you can see everything still claimable in one look.
