Sunday

Mobile game publisher with ad monetization

Overview

Sunday GmbH is a Hamburg-based mobile game developer and publisher known for hyper-casual hits like Cat Escape, Spinner Merge, and Mr. Pain, with ad-supported free-to-play monetization. It runs a proprietary end-to-end platform that handles game design, market testing, user acquisition, and performance marketing, giving it full control over its in-house and partner titles. It differentiates itself through vertical integration and a track record of very large download counts, plus a pivot from hyper-casual to hyper-personal, emotion-focused digital companions. Its goal is to build deeply engaging, care-driven mobile experiences at scale while continuing growth in the app ecosystem, supported by Applike Group and Bertelsmann investment.

Simplify's take

What believers are saying

  • Sunday updated its website October 3, 2026, showing active investment in the pivot.
  • Cat Escape passed 100M Google Play downloads and updated September 25, 2026.
  • LinkedIn updated November 3, 2026 says Sunday remains backed by Applike infrastructure and data.

What critics are saying

  • Hyper-personal repositioning is still branding, not a durable genre moat against Voodoo.
  • Cat Escape still drives the franchise; a hit decline would crush revenue quickly.
  • If companion games fail to scale, Sunday becomes a dependent studio inside Applike Group.

What makes Sunday unique

  • Sunday’s 2026 platform turns hyper-casual installs into “digital companions” with emotional hooks.
  • Cat Escape and Dog Escape anchor a 500M-download escape universe and proven IP.
  • Applike Group’s adtech stack gives Sunday first-party UA, monetization, and scaling infrastructure.

Brainamics Measures Your Player'S Brainwaves So You Can Make Better Games | Pocket Gamer.Biz | Pgbiz

One of the more arresting booths at our recent Pocket Gamer Connects event in London came was that belonging to Brainamics. Featuring a gamer happily holding a game controller while wearing a weirdly sci-fi esque headset. We wanted to find out more, and managed to have a quick chat with Brainamics CEO and Co-founder, Philipp Zent.It works like this: By popping a headset on a player, and measuring their EEG (what we'll call brainwaves for simplicity's sake), the system produces data that can be used to measure what emotions and sensations a player was experiencing. Happiness, frustration, boredom. AKA all things that game designers on all platforms need to bear in mind when producing a (potential) hit game.BrainfreezeThe benefits are obvious of course. Developers have struggled to know what's going on in their player's heads
