Short answer. The cash value of free spins before conditions is spins × spin value × RTP: 180 spins at €0.10 on a 96% slot are worth about €17.28 in expected winnings. Conditions then take their share. BitStarz wagers free-spin winnings 40× and gives one day to activate and one to use each batch; Pin-Up wagers them 50× within 48 hours; Roobet pays RooSpin winnings straight to the wallet with 7 days to use the spins; Duelbits does not state a requirement for Rookie Rush spins on its page. With a 40× requirement on €17 of winnings you must turn over €691, which on the same 96% slot costs €27.65 in expected losses, more than the spins were worth.
Formula
gross value = N × spin value × RTP
wagering cost = (gross value × multiplier) × (1 − RTP)
net value = gross value − wagering cost (ignoring caps and expiry)Net value is positive only when multiplier × (1 − RTP) < 1, i.e. multiplier < 25 at 96% RTP, < 33 at 97%, < 50 at 98%. At 40× and 50× the expected net value of free spins with wagering is negative on any slot below 97.5–98% RTP.

Example: 180 BitStarz spins
Assume €0.10 per spin (enter your actual value). Gross value 180 × €0.10 × 0.96 = €17.28. Wagering 40× = €691 of turnover, costing €27.65 at 96%. Net expected value about −€10. The spins are a reason to play, not a source of money. Because they arrive 20 per day for 8 days and each batch must be used within a day, missing a day forfeits that batch.
Example: 250 Pin-Up spins
Gross value at €0.10: €24. Wagering 50× within 48 hours: €1,200 of turnover, €48 expected loss. Net about −€24. The ×5 cashout cap on the main bonus does not apply to spins separately, but the 48-hour clock does.
FAQ

How much is a free spin worth? Spin value × RTP, typically €0.10–€0.20 × 0.96. 100 spins are usually worth €10–€20 before conditions.
Can I choose the slot for free spins? No; terms name the game (12 Coins, Burning Sun, Golden Mine, Aloha King Elvis!, Johnny Cash in the 1x-platform packages).
