Is the Casino Kings Casino Diamond Treasure Bonus Actually Worth Claiming?
Most casino sites simply restate the headline bonus figure. We break down what it is actually worth using the maths.
Welcome Bonus Expected Value Calculation
| Welcome bonus amount | £50 |
| Deposit match percentage | 200% |
| Wagering requirement | 35x the bonus |
| Total wagering required to clear | £1,750 |
| Expected loss at 96% slot RTP (4% house edge) | £70 |
| Net bonus value after clearing | £-20 |
This means the Casino Kings Casino Diamond Treasure welcome bonus carries negative expected value under standard conditions — the case for the majority of UK welcome offers.
What this means in practice: To unlock the £50 bonus at 35x wagering, you must place £1,750 in qualifying bets. At 96% average RTP, you will lose approximately £70 doing so — the bonus does not compensate those losses. Treat it as entertainment value rather than free money.
Assumes 96% average slot RTP and full wagering on slots. Table games typically contribute less — always check the full bonus terms before opting in.
