How to play Diamond Link: Mighty Sevens (members only)

Set your stake. Choose your total bet per spin. Wins are paid as multiples of this stake.
Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.

How winnings work (members only)

What 95% RTP costs per $100 wagered, the 1,429x max win at a $1 stake

The top prize is capped at 1,429x your stake. On a $1 spin that is $1,429; on $0.20 it is $285.80. When the cap is reached the round usually ends immediately.

What 95% RTP means

Expected return = stake × 95%
Over $100 of total bets, the long-run average loss is $5.00

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium volatility game.

The published hit frequency is 25%, meaning roughly one spin in 4.0 returns something — though many of those wins are smaller than the stake.

Features explained (members only)

4 features explained: free spins, respins, hold and win, gamble feature

Free spins

A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Hold and win

Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.

Gamble feature

After a win you can risk it on a double-or-nothing guess, such as the colour of a card. It does not improve the game's long-term return.

Strategy tips (members only)

Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.

2 more tips and a session planner

Bonus wagering: at 95% RTP, clearing $1,000 of wagering costs about $50.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
