Two seasons are ending and two playoff brackets are opening within 48 hours of each other, and that overlap makes this one of the busiest stretches on the calendar for new bettors to get their feet wet. The WNBA regular season wraps this week, with the playoffs tipping off Sunday, Sept. 27 — all eight teams jump straight into best-of-three first-round series (No. 1 vs. No. 8, No. 2 vs. No. 7, No. 3 vs. No. 6, No. 4 vs. No. 5).
MLB’s regular season closes out that same Sunday, and the postseason wastes no time following it, with the Wild Card Series opening Tuesday, Sept. 29. For a few days, the final week of the MLB regular season, MLB’s Wild Card round, and the WNBA’s opening playoff weekend are all live at once.

That kind of volume is exactly when Fliff’s welcome offer is worth a look. New users can claim up to $250 in Free Play with promo code LINEUPS.
How the Fliff welcome bonus works
Fliff isn’t a traditional real-money sportsbook — new users purchase Fliff Coins, a free-to-play social currency, rather than making a cash deposit.
- A qualifying Fliff Coins purchase comes with a matching bonus in Fliff Cash, the platform’s redeemable currency.
- Stacking multiple purchases is how users work toward the full $250 in Free Play value.
- Fliff Cash has to be wagered once (a single rollover) before it’s eligible for withdrawal.
- Cashing out requires a $50 minimum Fliff Cash balance and ID verification, with payouts available via bank transfer or Skrill.
Why this week is a good time to try it
The final week of an MLB regular season is usually when Wild Card and division races actually get decided, which means meaningful games practically every night before the Wild Card Series takes over Sept. 29–Oct. 1. Layer the WNBA playoffs on top — four best-of-three series all starting the same weekend — and new users get two sports’ worth of live games to explore moneylines, spreads, totals, and player props without needing to put real cash on the line first.
