Diamond Charge Hold and Win

About Diamond Charge Hold & Win

Diamond Charge Hold & Win is a 5 reel, 4 row slot built by Iron Dog Studio and distributed through the 1x2 Network platform. It went live on 3 September 2025 with 30 fixed paylines in the base game, a single bonus round, and no Free Spins anywhere in the maths. Almost everything points towards the Hold & Win respins, where bonus coins carrying printed cash values lock onto the grid and Collector symbols sweep them up.

Iron Dog has been putting out coin collection slots for several years, and this one strips the format back further than most. There is no Gamble, no scatter chase and no progressive pool sitting behind the reels. Anyone who prefers a slot with two or three competing bonus routes will find it narrow. Anyone who wants a single clear objective, filling the grid with coins before the respins run out, gets exactly that and very little else.

How to Play Diamond Charge Hold & Win

Stakes at Midnite start from £0.10 per spin. Wins pay left to right from the leftmost reel across 30 fixed paylines, and the paytable climbs from playing card royals at the bottom to the diamond at the top. Autoplay and a quick spin toggle sit in the control bar under the reels, and the paytable is reachable from the in-game menu at any time.

Bonus coins are the symbols that matter. They land across all five reels during normal play, each one printed with a cash value tied to your stake, and six or more of them anywhere on the grid start the Hold & Win round. Three respins run from that point. Every coin that lands sticks where it falls, and the respin counter resets to three each time a new coin or a Collector arrives. The round closes when the respins run out or every position on the grid is occupied.

Diamond Charge Hold & Win Features

• Hold & Win Round: Landing 6 or more bonus coins anywhere on the reels starts the round. It runs on 3 respins, the coins stay sticky for the duration, and the respin counter resets to 3 whenever a new coin lands.
• Collector Symbol: Collectors appear on reels 1 and 5 only. Each one gathers the cash values showing on the bonus coins in view at that moment, so two Collectors on screen together collect those values twice.
• Coin Shower: A random base game trigger that drops six bonus coins onto the grid and opens the Hold & Win round without the usual build up.
• Wild Symbol: Substitutes for the paying symbols in the base game and pays up to 100x stake for five of a kind, matching the diamond at the top of the table.
• No Free Spins: Diamond Charge Hold & Win does not include a Free Spins round in any market. The Hold & Win respins are the only bonus feature in the game.

Diamond Charge Hold & Win Theme and Symbols

The presentation pairs diamonds with electrical detailing. Gemstones and gold coins sit against a dark reel frame with current motifs running through the borders and the bonus round furniture, and there is no story or character set behind any of it. Iron Dog has gone for a clean, restrained look rather than a busy one, which suits a game whose whole appeal rests on watching coins stick.

Playing card royals fill the bottom of the paytable at up to 5x stake for five of a kind. Blue, red and green gems sit above them at 30x, 40x and 50x, and the diamond tops the standard symbols at 100x alongside the Wild. Bonus coins carry their own tiers, with bronze, silver and gold denominations paying 2x, 4.5x and 9x, and larger printed values appear on coins during the Hold & Win round, reaching as high as 1,000x on the top denominations.

Games Like Diamond Charge Hold & Win

• Blood Moon Hold and Win: Sits on the same distribution platform and uses the same coin collection framework, with a darker theme and a different respin structure.
• 3 Mad Frogs: Iron Dog's own catalogue, lighter in tone, and a useful comparison for anyone who likes the studio's build but wants more going on in the base game.
• Inspector Wilds: Another Iron Dog title, built around wild behaviour rather than coin collection, so the bonus rhythm is quite different.
• Serpent Gold Hold and Win: A close format match, with sticky cash symbols and a respin counter that resets on every new landing.
• Lucky 1000 Hold and Win: Similar coin collection maths with fixed prize tiers layered on top, worth a look if the 5,000x ceiling here feels restrictive.
