In-game currency.

Designed and launched in 2020


Could a new in-game currency for certain features mitigate the cannibalisation of the main level progression?

In 2020 I was part of a team that set out to learn more and founding a solution to the question above. All of this took place in the mobile game Candy Crush Soda Saga.

Purpose of the project

The reasoning behind this project was to see if we could mitigate the cannibalisation that other features within the game created to the main progression. This had become a problem because all experiences a player could engage with cost a heart-life. Which made them have to choose where to spend their limited resource, therefore we began exploring to add a new in-game currency which we later named Energy.


We assume that players 

will play more levels if we have a new in-game currency for side-content


We intend to prove this by

building a production prototype of a side-content feature where we give players the new in-game currency instead of the regular lives


We know we are right when 

we see an increase in the number of levels played for >60% of players without any loss of gross bookings

Result and what we accomplished

The project was a success of how it performed in the game but also how we delivered it.

This new in-game currency that we named Energy performed well in the feature we began testing it in. The best A/B-case had an increase in both the number of levels played and gross bookings. 

Our development went great because we met the deadline and it was a scalable solution. This created the foundation of having more areas of the game using Energy. 


Key metrics

The signals we were looking for were two things, the number of played levels and the gross bookings. 

When it came to the number of played levels we saw an increase between +1.2-1.4% in one of the A/B tests.

There was also an increase of +1.0-1.2% in gross bookings.

This made the in-game currency, Energy, being brought out to more and more players. By now 95% of players have Energy and it's recognised as a valuable resource seen from both a player perspective and a business perspective.

Approach of how I worked 

The work I did for this project can be described in three words; iterative, collaborative and transparent. 


The reason, why I use the word iterative, is because I started making early, simple and fast concepts. This approach helped me communicate and often align the team with what we were creating.   ​


One of my goals when working together with other people is to create a feeling of having momentum. This is only achieved if you can collaborate and trust your peers. A way of including and collaborating was the regular feedback sessions that we had during the whole project. 


Everything I did was being made in software and tools that everyone had access to. The work could be viewed at all times and I invited people to add comments, thoughts, and ideas.

Visuals of what I delivered

There were a bunch of things created for this project, I can't publicly share all of it but here's a selection of things I made. 


High-fidelity prototypes of how the experience was designed to behave. 


The early concepts of how to get the in-game currency into an existing feature. 


Research of how other games introduce different things to their players. 


Feedback was structured and focused to provide the most value.
