Why Bonus Mechanics Have Become Core to Game Design

Game design has had a long history, and one of the most dramatic recent changes is that bonus mechanics are now playing an increasingly central role. This change highlights the importance of bonus mechanics in game design. In the past, these may have been considered optional extras to the main game, but increasingly, these bonuses are becoming indispensable in both the design and development of a game and a major determining factor in how your players approach the game. They are no longer merely additional little rewards that are tacked on to the main game, but key components that build user engagement, and make the whole experience more rewarding for players.

In earlier games, bonuses were simple rewards for completing certain tasks and rarely featured heavily in the game’s main appeal. You could play the game without ever interacting with them and not feel you were missing much. Today, they are often a core part of the game’s mechanics, making them essential to the player's modern experience, which has made bonus mechanics game design an integral element.

Developers know that today's audiences expect excitement and variety from their games and bonus rounds offer both of these. Bonuses are no longer just a pat on the back to signal the end of a level or reaching some goal: now they offer new challenges to the players, unlock exciting extra functions, or change the underlying game mechanics to keep players on their toes.

Part of this change may be due to differences in how the public as a whole approaches gaming. Research suggests that in 2021, more than 70% of Americans played some kind of video game. It’s clear from this that gaming has become a far more mainstream activity than it once was. It’s no longer niche or exclusive and as a result, people don’t want bonus content that can only be unlocked by completing some arcane series of unlikely actions at just the right moment and that only a few players will ever discover. They want the bonuses that are part of the main game, and that can be accessed easily each time they play. This reflects a shift in bonus mechanics game design strategies.

So, we’ve seen some big changes. One type of game that illustrates this trend wonderfully is the casino jackpot slots. In the past, slot games were usually won by lining up matching symbols and that was all there was to it. These days, the vast majority of slots will have some kind of bonus round that players can trigger, and getting one of these is often far more exciting for the average player than getting three symbols in a row. In that sense, it sometimes feels like accessing the bonus round could be considered the game’s main objective, while matching the symbols has been reduced to an optional extra.

This new approach to game design encourages players to feel more invested in the game, and the rush of excitement when unlocking a bonus level often far outstrips the enthusiasm of winning a regular round. These immersive online casino jackpot slots not only capture the thrills that the old-fashioned mechanical slot machines provided; they build on that with bonus rounds that offer up new mechanics and surprising twists on the gameplay. Rewards are a key element of engagement, and casinos certainly know how to offer them!

One major element that increases player engagement in bonus rounds—like free spins and mega wins—is giving them more influence over the outcome. This helps them feel more invested in the game as a whole and more confident in their skills as a player. Games that do this well are likely to rapidly gain loyal fans and an enthusiastic player base.

Take, for example, the post on Instagram “When you find your go to game” where the bonus mechanics (e.g., the extra free spins and big wins) show you how player retention is incentivized through the power of engaging gameplay loops, coupled with bonuses that showcase your progress. In this video, the players express joy at gaining progression-driven free spins, which results in an overall better experience.

A well-designed bonus system produces emotional investment in the players and forges a cycle of anticipation, participation, and reward. These are the moments that make bonus features so effective, providing a way to keep players interested and perpetuating a long-term connection with the game based on solid bonus mechanics game design.

Bonuses play on several key psychological incentives that keep players engaged. They offer something to look forward to, creating anticipation and preventing the game from feeling static or predictable. Players don’t know when the next big payoff might come or where a special round will pop up, and this makes every round feel more exciting.

Moreover, bonuses give players a sense of progression, using the positive feedback of tangible rewards. Unlocking bonuses helps them feel that they are making progress within the game. Such positive feedback provides an extra incentive for players to continue playing. Here is an overview of some of the core features that make bonuses so fun:
