The welcome: 500K GC + 25 free spins + $24.99 → 75 SC
- No-deposit: 500,000 Gold Coins + 25 free spins
- First-purchase pack ($24.99): 75,000 GC + 75 SC
The 25 free spins no-deposit is unusual in sweepstakes. Most operators credit Gold Coins and Sweeps Coins; free spins are typically a real-money casino welcome mechanic. Stackr’s 25 free spins likely apply to specific featured slot titles with documented per-spin SC equivalents.
The 75 SC at $24.99 (3 SC/$) is competitive with the cohort baseline.
Provider catalog: 19 studios, including FIVE tier-1 high-volatility headliners
