Use the formula:
Effective value = Bonus amount - (Bonus × Wagering × House edge)
For slots (4% house edge):
• £100 bonus at 30×: £100 - £120 = -£20 EV
• £50 bonus at 20×: £50 - £40 = +£10 EV
• £30 bonus at 20×: £30 - £24 = +£6 EV
Look at:
• Wagering requirements
• Game restrictions
• Time limits
• Maximum bet
• Maximum win
• Casual players: smaller bonuses with low wagering
• High-roller players: larger bonuses with low wagering
• Slot players: any bonus works
• Table game players: most bonuses don't work
Always read the bonus terms:
• Look for hidden restrictions
• Check maximum win
• Check eligible games
• Check time limits
Largest bonuses often have worst terms:
• Higher wagering
• Lower game contribution
• Shorter time limits
Compare effective value, not headline.
Many players don't read bonus terms:
• Wagering requirements
• Game restrictions
• Time limits
Read the terms before claiming.
Some games don't contribute to wagering:
• Playing restricted games doesn't progress wagering
• Use eligible games only
Exceeding max bet during bonus:
• Forfeits bonus and winnings
• £2 standard max bet
Stay within max bet limits.
Bonuses expire if wagering not complete:
• 7-30 day time limits typical
• Forfeit bonus and winnings if expired
Complete wagering in time.
In addition to welcome bonuses, some UK casinos offer no-deposit bonuses:
• 50 free spins no deposit
• No wagering
• Cash winnings
• Just for registering
• 10-50 free spins no deposit
• 50×+ wagering
• Smaller maximum wins
• For new registrations
No-deposit bonuses are rare at UK casinos but exist.
High-roller players should look for:

• Requires larger deposits
• Higher EV for high-rollers

Claim Bet365's £30 welcome bonus: 20× wagering is the lowest at any major UK casino.
Even the best welcome bonus may not be worth claiming:
• Wagering is 50×+
• Time limit is less than 7 days
• Game restrictions are too strict
• Max bet is too low
• Max win is too restrictive
• You want fast withdrawals (bonuses block withdrawals)
• Wagering is 20× or less
• Time limit is at least 14 days
• Game restrictions are acceptable
• Max bet is reasonable
• Max win is not too restrictive
For most UK players, claiming welcome bonuses is a slight positive or marginal EV. Treat them as entertainment, not profit.
Welcome bonuses encourage larger deposits than players might otherwise make. To manage:
• Set deposit limits
• Don't increase deposit for bonus
• Use time-outs
• Self-exclude via GAMSTOP if needed
Bonuses should enhance entertainment, not drive spending.
