Tile Games Level Design: Best Practices for Testing Like A Pro

In tile puzzle games, the engaging level design is butter and bread, and the very thing players spend time playing. In this article, we talked with Renald Gazar, Lead Level Designer at Room 8 Studio, about levels of quality assurance – so, what does it take to polish your levels? Let’s find out.

Renald Gazar is a Lead Level Designer in Room 8 Studio. Being a professional level and game designer, in recent years, Renald was involved in creating such match-3 market hits as Angry Birds Dream Blast, Meow Match, Cat Force, and others. His expertise allows him to lead a team of level designers successfully. 

What Is a Quality Assurance in Game Level Design?

In tile puzzle games, level design QA means ensuring that the level matches its target level difficulty and UX requirements. For example, ‘easy’ levels have a setting of 1 win per 2 attempts, feature lots of VFX with elements matching easily, and a player feels like every move is great. The harder the level, the more attempts a player is expected to perform per every win.

The Core Value Of QA In Level Design

Level testing allows game and level designers to find and fix the level’s problems before they go live or even polish them after the release, so it’s an essential step in the game development.  

Ideally, level difficulty forms a proper difficulty curve, which makes up the player’s UX, and the game feels just right: not too easy to be bored with and not too hard to quit altogether. Plus, they should feature game mechanics, and there are unique ones for every game out there to make the puzzler stand out from competitors. Let’s start by outlining the most widespread issues of QA in level design.

  1. UX and mechanics issues. In addition to checking proper difficulty, sometimes the mechanics combined may lead to unexpected ways to pass the level, revealing its vulnerabilities. This is tested during the QA phase, and the level tester takes down notes, describing the particular problem.
  2. Live ops KPIs problems. We usually look at the churn rate and monetization of the level. ‘Easy’ levels work for retention, they should feature visual effects and feel great for the player, so both churn rate and monetization should be low, as the player does not need additional boosters to pass the level. ‘Medium’ levels also work for retention, feature wow-effects, leave that ‘near-win’ feeling, and may have slightly higher monetization and low churn rate. These levels usually feature some kind of trick or obstacle and feel a bit harder, but be totally passable without any paid boosters. An finally ‘hard’ levels, in which we include so-called ‘extreme’ and ‘skill’ levels, have only 1 win per 8-10 attempts, so they can be very frustrating. These levels are made to nudge a player to pay, and while they are passable, churn rate may be higher but monetization numbers should be high as well. 
  3. Bugs in the game and editor. While game testers usually perform all kinds of tests before going live, some problems with the game engine and editor are spot during level design QA phase. The level tester takes down notes about this and helps fix the problems.

QA Rounds In Level Design

Depending on the game development stage and its requirements, there may be slightly different stages in the level design QA process. However, we recommend these two as a base for every project.

Initial testing

Testing is done by the level designer who created it to ensure the level matches the requirements.

Internal testing

Our team of level designers does internal testing. Usually, one level is tested by three people of different match-3 skills. They could be working on the same project as a level designer who created it or on the others. Every level is played several times, matching the goal amount of attempts per every level. The tester also puts down any comments they may have on the game mechanics, bugs, or even level editor faults. It’s good if a level editor has functionality for placing these comments.

After the level is played the needed amount of times, we gather the statistics and see if there are any problems and if the complexity and UX match the requirements of this particular project.  After that, the lead level designer fine-tunes the level if needed, and the level goes into a ‘level pack,’ which is shipped to the customer weekly.

Feedback, analysis & polishing: final and live tests

If the game is in the production stage, we receive comments from the customer on difficulty and UX, fine-tune the levels according to them, and send the final pack. 

If the game is live, sometimes customers upload the newly created levels live and gather live ops stats; usually, we obtain the needed stats after 1-3 months after the level release. So to polish the levels, we look into this data, and it’s our task to make sense of it and translate it to changes in the level design. Usually, we look into:

  • Average and/or median number of attempts, same for attempts to win
  • Churn 
  • Monetization

For example, a difficult level may bring a lot of money but have a pretty high churn rate. In this case, we can be okay with the churn rate; but if a hard level doesn’t bring enough money, which is the whole point, they will look into how we can make it easier and more engaging. If the churn rate is low but the income is low as well, it means that the level is too easy, and we make it harder. 

Our Experience 

In our experience, level design QA and polishing take about the same time as level creation or more. Add documentation and final testing – you get a rough idea of how important is a proper process to make this work. 

At Room 8 Studio, we have a focused team of level designers dedicated to creating and polishing levels we do for our clients. This enables us to test levels manually, ensuring they match client requirements.

While there is automated level design quality assurance, they usually poorly do the work like bots. They have to imitate a real person playing, make mistakes, be frustrated, etc., which can only be achieved at some limited level.
