Yet Another Merge Game is an Idle Game by VeproGames released in 2020. You have mergers spawn on the board every few seconds. Each merger produces Matter and merges with another upon collision, raising its tier by 1 and multiplying Matter production by 5. Once enough Matter is accumulated, you can buy upgrades and interact with new mechanics to progress even farther.
A major update was released in 2021. It added Molecules as a resource unlocked upon reaching merger tier 420, a few new upgrades, new backgrounds and merger designs, and other small fixes.
It is playable on Github

This game provides examples of:
- Adam Smith Hates Your Guts: In addition to the typical exponential cost growth found in idlers, the game employs several other cost scalings that trigger every set number of levels to ensure that production doesn't increase too quickly. The cost growth of Better Mergers becomes double-exponential at level 10,000 since that's the intended endgame (you unlock the last background at merger level 10,000).
- Cap:
- Some of the upgrades have a cap ranging from 10 to 100, mostly those related to random chance or decreasing requirements.
- Each molecule's power is capped at ^10, which is reached at v90,001.
- Color-Coded Item Tiers: Most of the early merger tiers are recognisable almost purely by color. Later ones add small particles and other smaller mergers attached to them.
- Diminishing Returns for Balance: Each upgrade for Molecules multiplies the merges needed for the Molecule Level by 0.99x, but this is eventually softcapped and they'll stop decreasing nearly as much to not make them max out too early.
- Empty Levels: Thanks to Diminishing Returns for Balance, Prestige's Matter Boost in the lategame gives almost nothing compared to Isotopes'/Molecules' Matter Boost, which outright doubles your matter gain each time it's bought.
- Export Save: Pressing export gives you the 1KB+ save file which can be imported by pasting it into an in-game window. The game gives a stern warning to export frequently.
- Loading Screen: There's a loading screen before the game starts which shows a merger at a random level below 100.
- Lore Codex: The Mergepedia catalogues what mergers the player has reached, as well as their production and base production rates.
- Luck-Based Mission:
- A lot of your progress in the early game relies on whether two suitable balls get to collide with each other (which depends on factors, such as speed, size, and direction). Sometimes this can happen very quickly, other times you will need to wait minutes.
- Initial isotope generation starts at a 1% chance per merge. It can be quickly increased, but it still has a low chance until much later.
- New Game Plus:
- At 1e15 matter, you gain access to Prestige, where you reset all mergers, Matter, and Matter upgrades for Quantum Foam that boosts overall Matter production by 1% each and four new upgrades.
- Starting from 1e11 Quantum Foam, you can buy a Quantum Processor Core, but this resets all mergers, Matter, Matter Upgrades, Quantum Foam, and Foam Upgrades. As you can only have up to five Cores, it's pretty short-term.
- Quantum Mechanics Can Do Anything: Each Quantum Processor Core is used to multiply matter production by x25, which can be upgraded with Isotopes.
- Please Subscribe to Our Channel: The "Subscribe" button at the bottom links to the creator's YouTube channel so you can do that. Clicking on it grants a 3x Matter boost that eventually goes up to 729x.
- Purposely Overpowered: The Automatic Foam upgrade grants you the ability to gain Quantum Foam every second, which is absurdly powerful as it grants a multiplier and makes upgrades closer every second, effectively rendering the Prestige system next to superfluous. That's why it costs 10,101,010 Isotopes for even the first level at 0.1%, as getting it anywhere before that point would trivialise a large part of the game.
- Random Drop: Once you unlock Isotopes, a merge has a 1% chance to produce one, which can be increased up to 100% with upgrades.
