Which of the two
They're close, and they split cleanly on what you're there for:
- Betting is the point → Sportzino. 40+ sports against 30+, and a free-entry ladder that lets you actually get to a bet without buying coins.
- You want a casino that also takes bets → Legendz. The book is narrower but the casino is roughly three times the size, and the payout rails are the best in this comparison by a wide margin.
- Getting paid quickly matters most → Legendz, comfortably. Instant push-to-card against Sportzino's bank-transfer-only cash lane isn't a close call.
The other shape: standalone social sportsbooks
The two rooms above are casinos that also take bets. There's a second shape entirely — apps that do sports and nothing else, on the same dual-currency sweepstakes model. We've now reviewed all four of them, and they generally reach more states than the casinos do:
Standalone social sportsbooks, reviewed
| App | Score | Reach | Redemption | The catch |
| Rebet | 3.7 | ~41 states | ~$10–20 min, up to 4 days | $0.75 fee per withdrawal, bank only |
| Fliff | 3.6 | All but 5 states | $50 min, 1–3 days, fee-free | Can't redeem in ~20 states it works in |
| Onyx Odds | 3.2 | ~41 states | $20 min | ACH only, up to 30 days |
| Thrillzz | 3.0 | 18 states out | $50 min | Stated ceiling of up to 60 days |
Rebet is the one to start with if the two ranked rooms don't reach you — widest map of the four, lowest floor, and it covers Texas, Florida and Georgia. Fliff is the better-built product but you must confirm your state is on its redemption list and not merely its availability list; those are two different maps and roughly 20 states sit in the gap.
They're not ranked alongside Sportzino and Legendz above because they aren't the same product — a score for a casino-with-a-book folds in a game library these apps don't have. Compare within a shape, not across two.
What these are not
Three different products get called "sports betting apps" and they aren't interchangeable:
Sweeps sportsbooks compared with DFS apps and regulated sportsbooks
| Sweeps sportsbook | DFS / pick-em | Regulated sportsbook |
| Examples | Sportzino, Legendz | PrizePicks, Underdog, Sleeper | DraftKings, FanDuel, BetMGM |
| You wager | Stake Cash | Cash entries | Cash |
| Bet type | Standard sports markets | Player projections, more/less | Full markets incl. same-game parlays |
| Purchase required | No — free entry route exists | Yes | Yes |
| Where it works | Most non-regulated states | Varies, own restricted list | Licensed states only |
If you're in a state with a licensed book, that's usually the better product — deeper markets, more liquidity, clearer legal footing. Sweeps sportsbooks exist to serve the states where that isn't an option. We cover DFS and the regulated books in The Vault.
Both rooms above carry legal risk you should factor in. Sportzino faces two class actions arguing its dual-currency model is illegal gambling; Legendz has an open Illinois cease-and-desist. Neither is a prediction that anything happens to your account — but the sweeps sportsbook model is the least legally settled corner of an already unsettled category, and you should keep balances there smaller than you would elsewhere.
