This game involves using bubbles to free petrified Pojikemos in underground passages. Defeat skeletons and floor keepers to progress to lower floors. Skeletons drop bones, which you can collect. Aim to complete the collection. There is a low chance of rare Pojikemo poses, and an even lower chance of rare gold poses appearing. Rare poses are stored in an album and can be collected. Aim to complete the collection. You can change the button position to your liking in the settings, so it fits whether you hold your iPhone on the left or right side.

Verdict
The clearest difference is ads: quantum gates at none against Bubble Hero.'s shown. quantum gates also leads on device support (3 vs 1). Bubble Hero.'s advantage is update cadence (every 2 days vs every 6 weeks). On price, in-app purchases and iOS requirement there is nothing between them.
