Dragon Eggs On Dragonvale

The breeding mechanic explained

Dragon Eggs are the reward you get when you successfully breed two dragons at the Breeding Island. Gameloft's mobile title has been around long enough that most people understand the basic loop, but there are a few quirks that nobody bothers documenting properly. I spent roughly three years grinding through element combinations and learned this the hard way. When you pair two dragons, the game calculates a random outcome based on the combined elements of both parents. If the resulting egg matches a dragon in your current park, you don't receive the dragon itself — you get an egg instead. This means you can breed the same species repeatedly without it being wasted effort. The egg hatches into a duplicate, which you can then sell or use for transferring to other islands.

How Dragon Eggs On Dragonvale actually work in practice

The incubation timer is the main thing people complain about. A common dragon takes four hours to hatch on a standard phone. Mythical dragons can sit for up to twenty-four hours. The game does offer a speed-up feature using Gems, but spending currency just to skip waiting is a design choice that feels aggressive to a lot of players. I just let them sit and use the time to reorganize my island layout. Here's a specific problem I ran into back in 2018: I was breeding a T-Rex, which requires both Cold and Metal elements. I had every single parent combination that should produce it. Got the egg. Started the timer. Everything seemed fine. Three hours in, the egg just... didn't hatch. Turns out my battery optimization settings on my phone were killing the app in the background. The timer was paused while the process was technically running. I had to go into my phone's app settings and whitelist Dragonvale from battery restrictions. After that, every egg hatched on schedule. This isn't documented anywhere in the game itself. Element combinations matter more than you'd think. The game uses a hidden probability table behind the scenes. Breeding a Fire and a Water dragon doesn't always give you Water. You can get Lightning, Cold, or even a random common dragon depending on the roll. The official wiki has decent coverage of known pairings, but the actual probability distribution isn't public information.

Another counter-intuitive detail: having more breeding structures open doesn't increase your odds of rare spawns. It only increases how many simultaneous breeding attempts you can run. The probability stays identical whether you're using one tent or every single slot you own. People waste Gems building extra breeding islands thinking they'll get better results. They don't. The egg transfer system is where this gets useful. Once you breed a dragon you already own multiple times, those extra eggs become a form of currency. You can trade them with other players through the Trading Plaza. A common Rare element egg might fetch several thousand Gold, while a Mythical egg can go for tens of thousands depending on demand at the time. I've seen seasons where trading became the primary income source for players who didn't want to grind for Gold through the standard dragon feed cycle. There are scenarios where this system completely breaks down. If you join a new village and have no established trading relationships, you're starting from zero. There's no market liquidity until you build that reputation. New players typically can't move eggs quickly and end up sitting on inventory that has no buyer interest yet. The workaround is just patience — join active villages with plenty of traders rather than isolated ones with nobody online.

If you're looking to download the game, it's available free on iOS and Android through the standard app stores. Gameloft still maintains it actively as of 2025. The core breeding loop hasn't changed substantially since launch, so any guides you find from earlier years will still apply to current gameplay.
