Hold & Win Slot · Onlyplay
Rush for Diamonds: Hold and Win is a slot from Onlyplay — not to be confused with Diamond Rush Express, Red Tiger's Diamond Rush, or other similarly named titles from different studios. This specific game runs on a 5×3 grid with 20 paylines, RTP 97%, and a four-tier jackpot system layered on top of its Diamond Respin mechanic. Free demo is available at several partner casinos.
At 97% RTP this slot outranks most of its Hold & Win category — the typical range runs 95–96.5%. The 35.42% hit rate tells a similar story: the Diamond Respin phase fires more often here than on comparable titles, which matters if you're evaluating how long your session budget stretches.
Hold & Win started as a Wazdan mechanic and turned into its own genre. The difference from a regular slot: you don't just spin and wait for a line match. You collect special symbols across multiple attempts, locking them in place, building a combination over several respins.
In Rush for Diamonds, the mechanism works with Diamond symbols specifically:
Diamond Respin stays on during Free Spins. So if 6+ Diamonds land inside a free spin, the Hold & Win phase kicks in exactly as it does in the base game. Two separate bonus layers that can overlap.
Bonus Buy lets you skip directly to the bonus game without waiting for a natural trigger. The buy-in is 100× your stake — consistent with Onlyplay's typical pattern across their Hold & Win titles. Not all jurisdictions allow Bonus Buy — if you're in Germany, check whether your casino has this feature active under local regulations.
Rush for Diamonds carries four fixed jackpots that activate during the Diamond Respin phase.
Tier values follow Onlyplay's established Hold & Win pattern from titles like Pyramid Coins and Coin Clown. Exact sizes are based on pattern-matching — confirm in-game for the definitive values.
The jackpot tier adds a secondary win layer on top of the standard Diamond cash accumulation. It's possible to land a Grand jackpot symbol mid-respin, which resets the counter and adds the jackpot payout to whatever Diamonds are already locked. The tier values above follow Onlyplay's established Hold & Win pattern from titles like Pyramid Coins and Coin Clown.
The game is available at Rainbet, Winz Casino, Fairspin, ltccasino.io, and Stake.us. For US players: Stake.us operates as a social casino under US law. For Nigeria and Kenya: Rainbet and Winz Casino are crypto-friendly and accessible in Africa.
Free demo is available at SlotsLaunch (no registration) and Winz Casino. Try it before committing real money.
Bets run from $0.10 to $50 per spin.
Each spin can potentially trigger the Diamond Respin phase if 6+ Diamond symbols land.
Once Hold & Win phase starts, new Diamonds and Jackpot symbols keep extending your respin chances.
All 15 positions locked = 2,185×. Each locked Diamond adds its cash value to the total.

97% RTP is a clear gap over the competition — most Hold & Win games sit between 95% and 96.5%. Where Rush for Diamonds loses ground is the max win ceiling: Money Train 4 goes to 50,000×. If you're looking for medium volatility, a jackpot layer, and consistent hit rate — this is the lane.
