Super Slots 64 Casino

Context

This mobile slot machine game draws inspiration from Mario video game themes, particularly the level break mini-games found in Mario 2 and 3. It’s my take on those classic mini-games, enhanced with additional features such as Match card, Kart race betting, a Plinko-style mini-game, and a spin-the-wheel bonus mini-game. The project is intended to serve as a work-in-progress, allowing me to further develop my game design and development skills over time.

Summary

This game was initially designed to be free to play, with the aim of generating income through ad-based support. By incorporating advertisements, revenue could be generated as gameplay increased, directly correlating with ad views and the potential for click-traffic. To address the challenge of increasing gameplay time and retaining players who quit prematurely without engaging with ads, I sought to investigate the underlying causes.

How can I increase gameplay time?

To uncover potential solutions, I leveraged the game’s audience of several thousand players. Through user interaction experiments, facilitated by Google Analytics and anonymously submitted data surveys capturing players’ in-game actions and reactions, insights began to emerge.

In the end, the solution was found in broadening the range of gameplay experiences and implementing a redesigned user interface!

To delve deeper into how this conclusion was reached and the subsequent outcomes, read on.

Final UI Design

Project Goals

  • Increase review generated by Ads
  • Increase player game time
  • Increase ad display time and interstial ad placement, without hurting player retention

Project Process

I utilized the classic design process rooted in scientific methods, but expanded it to encompass the human element, emotional connection, risk/reward, and overall experience.

 

Empathize: What are the players seeking from this gaming experience?

Define: What motivates them to choose a slot machine game over other genres?

Ideate: Introduce modifications through successive mini-updates and monitor statistical feedback.

Prototype: Develop new mini-games and analyze statistics to gauge player response to each new experience.

Test: Deploy competing updates using Google’s testing system, which automatically distributes variations to a balanced percentage of my audience.

Implement: As the variations began to yield desired effects, these versions were permanently integrated, replacing the original designs and gameplay mechanics.

User Play Testing

Recuitment

Utilizing Google Play’s testing publication feature, I could roll out diverse updates to assess their impact. This enabled me to test iterations across thousands of players spanning multiple countries, with a particular focus on my largest audiences, ranked by quantity: Mexico, Brazil, and the USA.

 

Research

Based on comprehensive statistics gathered over time, it became evident that players tended to spend more time in the game when provided with a break every 3-5 minutes, with these mini-game breaks lasting no longer than 1-1.5 minutes.

Further research into the realm of slot machines and regional cultural preferences revealed that Brazil and Mexico exhibited above-average interest in slot machine mobile apps. This, coupled with the lower graphic requirements typical of the genre, aligned well with the prevalent lower levels of technology in use in these countries. Additionally, an essential factor that emerged was the consideration of internet bandwidth and phone storage size.

Planning Process

How do I increase player game time?
Initially, gathering data was crucial to understand where players dedicated their time. To achieve this, updates were released with tracking codes, encompassing Google Play statistics, Apple App Statistics, AdMob Statistics, and custom activity tracking codes anonymously transmitted to my private server.

Fixing the Little Things

Considering the diverse language demographics of my audience, I undertook a redesign of the entire User Interface. This redesign prioritized symbols over text to convey information to players. Surprisingly, player retention increased following this adjustment, indicating a positive impact on player satisfaction attributed to the UI overhaul.

Moving forward, I aim to utilize symbols over text whenever feasible to convey information clearly. While not all information can be effectively communicated through symbolism, it’s worth investing the time to determine its viability.

USER INTERFACE / EXPERIENCE

Transitioning from text to symbols not only enhanced the interface’s aesthetics but also fostered a greater sense of engagement during gameplay. This conclusion was drawn from observations of numerous players across various age groups, coupled with follow-up inquiries such as:

  • How appealing does this gameplay appear to you?
  • Did you comprehend which action to take?
  • Were you confused by any specific icon?
  • Did you locate the button where you expected it to be?
  • What outcome did you anticipate upon tapping this button?
  • Plus several other queries addressing different aspects of gameplay.

UI and Art Sheets

Here are three art sheets employed in Super Slots 64. They were utilized for animation, language-based titles, and for all buttons and UI elements. This approach ensured consistency in design across various screens and menus, guaranteeing a cohesive visual experience throughout the game.

Buttons and UI – designed on one sheet to increase image continuity throughout the app

Animated Sprites – classic use of sprite sheets to animate characters and slot icons

Titles – key languages (English, Spanish, Portugues) were chosen to have custom titles made to localize content

Impact

Throughout its lifespan, Super Slots 64 underwent several UI changes while retaining its original design concept. Influenced by user feedback and personal growth in design expertise, the UI transitioned toward a symbol-based system, marking an improvement in my skills as a designer.

The results were impressive:

  • Player retention increased by approximately 15%.
  • Time played saw a notable increase of 21%.
  • The average rating climbed by 9%.
  • Retention rates in non-English speaking countries skyrocketed by an astounding 132%!
