Yarn Loop is a sort puzzle game by Combo Games, released in November 2025, and it has scaled past $150K+ in daily IAP revenue, according to AppMagic.
What’s interesting is how it builds on the success of Pixel Flow, arguably becoming the second major hit in this emerging conveyor-belt sort puzzle space, while carving out its own niche.
Let’s take a look at the decision behind this sort puzzler hit.
Appealing Theme
Instead of shooting cubes like in Pixel Flow, the game shifts to untangling yarn onto bobbins, which feels more tactile, relaxing and broadly appealing, especially to a wider female audience. This thematic shift, combined with strong visual polish, allows the game to retain the proven core gameplay of rotating conveyor belts and dexterity-based swapping, while avoiding the feel of a direct clone and expanding its audience reach through stronger emotional resonance.
Balanced Progression
The game features deterministic puzzles, allowing players to improve with each attempt, supported by clear difficulty labeling that sets expectations upfront. Boosters and new mechanics are introduced gradually, keeping the experience fresh while maintaining a smooth learning curve. Additionally, the game offers a leaderboard which adds an optional layer of competition for players who seek it. The game’s meta system borrows from publishers previous game, Cube Busters, incorporating minion style elements to enhance the overall game feel. This is further reinforced by the LiveOps system, which is introduced early and even teases content far ahead in advance, giving players clear long term goals.
Hybrid Monetization
The game combines both IAAs and IAPs to monetize players. Interstitials begin at level 20, while RV ads, such as level reward multipliers, are introduced at level 15. Additional RV placements are limited to life refills, keeping ad exposure relatively controlled. On the IAP side, the game features ad removal offers, time-limited deals, and various bundles in the in-game shop. Monetization is further reinforced through soft currency gating for boosters and revives, along with well-placed loss aversion moments at fail screens.
Genre Insights: Sort Puzzle
When looking at the sort puzzle subgenre, Pixel Flow is currently leading the charge in this highly competitive market where only 10 games have surpassed the $1M/month IAP benchmark out of 4900+ games, putting the success rate at roughly 0.2%. What’s notable is that, among these top-performing games, 4 are conveyor belt puzzlers and 6 were released in 2025, highlighting how recent design innovations are driving the category forward.
