Bulldozer: Slot Overview
Cock-a-doodle-doo! Prepare to harvest some fun wins in a fresh slot release from Iron Dog Studios (1×2 Network). The action is set on a sunny farm, complete with a farmer, hay bales, roosters, rams and, most importantly, bulls. This upbeat blend of rural life and animals creates an easygoing experience that should appeal to plenty of players—particularly anyone who enjoys classic hold-and-win style slots.

Bulldozer is a medium volatility slot with a default RTP of 96.07%, and it also comes in reduced RTP editions (94.02%/88.03%). Play unfolds on a 5-reel, 3-row grid featuring 20 fixed paylines for forming winning combos. Stakes range from €/$0.20-€/$50.00, and the game is available on both mobile and desktop. If you’d rather skip straight to the higher-upside action, there’s a bonus buy that lets you purchase 10 spins for 71 times your stake, or 20 spins for 142 times your stake, or even 30 free spins for 214 times your stake. The Hold and Win feature itself isn’t available to buy, but in testing the hit rate didn’t feel overly punishing.
Bulldozer: Slot Features

This countryside slot brings to mind Play’n Go’s recent 2022 release Animal Madness, although beyond the theme it doesn’t stick to a plain, standard hold-and-win formula. Iron Dog has layered in additional mechanics to help it stand out, such as Spreading Wilds, Coin Collection, Free Spins, and a hold-and-win round.
Bull Wild
This is where the bulldozer plays its part. Bull Wilds can land on the reels and act as substitutes for all non-special symbols. If a Bull Wild and a Bulldozer symbol appear on the same spin, the Bull Wild will charge towards the nearest bulldozer to replace the symbol, leaving a trail of Wild Bulls behind it—similar in feel to ELK Studios’ popular Toro series. Landing a full line of Bull Wilds pays 250 times your bet. This mechanic can trigger in both the base game and the free spins.
Coins
Coins may show up on all reels, and hitting 5 or more coins activates the hold-and-win feature. If the feature is triggered during free spins, a “W” Coin will replace all non-special symbols. When a coin lands, it flips to reveal a multiplier that applies to any win line it contributes to. If you manage to land two multipliers on the same win line, they will multiply each other.
Free Spins
Hitting 3 or more scatters starts the free spins feature; 3, 4 or 5 scatters award 10, 20, or 30 free spins, respectively. In free spins, both the Bull wild and coin features remain active, with the addition of a +1FS coin. On top of that, the wooden cannon appears more often than it does in the base game. It shoots coins onto the reels to boost your chances of setting off the hold-and-win feature.
Hold-And-Win
In either the base game or during free spins, landing 5 or more coins will trigger the hold-and-win feature. The usual hold-and-win format applies: you get 3 spins, and each time another paying coin lands, the respin counter resets to 3. Jackpot coins can also appear, and landing one awards a prize from 50 times your stake for the Mini Jackpot up to 750 times your stake for the Major Jackpot. Fill the screen with paying coins to receive 2500 times your stake.

Bulldozer: Slot Verdict
Reviewing yet another hold-and-win slot isn’t always the most thrilling assignment, but Bulldozer includes enough tweaks and extra features to keep casual players engaged. More serious slot fans, however, may not be blown away by the idea of getting stuck into farm work. And while Bulldozer won’t be dishing out the kind of monster results seen in earlier Iron Dog Studio successes like Pirate Kingdom Megaways or 1 Million Megaways BC, its reasonably strong potential could still be a good reason for experienced players to give it a spin.
On the topic of potential, Spreading Wilds combining with the Bull Wild can deliver sizeable base-game hits, especially since a full screen of wilds awards the highly sought-after 5000x payout. Overall, hold-and-win fans should find something to like in Bulldozer, as there’s room for some solid wins. The gameplay is perfectly fine too—but if this style isn’t your thing, Bulldozer probably won’t change your mind.
