What’s a Mini-Game? The Anatomy of Fishing Mini-Games

Fishing ‘mini-games’ are common in many contemporary video games. But what makes certain fishing-related video gaming elements into a ‘fishing mini-game’ per se and not merely a ‘fishing mechanic’? I answer this by examining how fishing elements vary from one implementation to another. Through analysing eight recent games with fishing, I identify and categorise a list of features where different implementations may vary. The resultant framework can assist designers to implement differently to cater to various player types and achieve specific goals. I also make a first attempt at distinguishing fishing mini-games from other fishing elements in video games. I identify two core considerations that, in my view, are crucial in rendering certain gameplay elements, but not others, a ‘mini-game:’ (i) gameplay-wise, the mini-game should be substantially different from other elements of the overarching video game and (ii) engagement with the mini-game should not be compulsory or effectively so.

“…Efforts have been proposed to minimize the disruption of a player's game experience through HIPs in a way that is seamless within the game, such as by integrating mini-game challenges (Chow, Susilo, and Zhou 2010), or by adding random variations in key aspects the game, such as item locations. One limitation of these approaches is that authors must also create content that does not necessarily create a better experience for the player in order to satisfy an orthogonal security requirement.…”

Bot detection is an emerging problem in social games that requires different approaches from those used in massively multi-player online games (MMOGs). We focus on mouse selections as a key element of bot detection. We hypothesize that certain interface elements result in predictable differences in mouse selections, which we call spatial game signatures, and that those signatures can be used to model player interactions that are specific to the game mechanics and game interface. We performed a study in which users played a game representative of social games. We collected in-game actions, from which we empirically identified these signatures, and show that these signatures result in a viable approach to bot detection. We make three contributions. First, we introduce the idea of spatial game signatures. Second, we show that the assumption that mouse clicks are normally distributed about the center of buttons is not true for every interface element. Finally, we provide methodologies for using spatial game signatures for bot detection.

The concept of reverse Turing tests, or more commonly known as CAPTCHAs, for distinguishing between humans and computers has been around for many years. The widespread use of CAPTCHAs these days has made them an integral part of the internet for providing online services, which are intended for humans, with some level of protection against automated abuse. Since their inception, much research has focused on investigating various issues surrounding the design and security of CAPTCHAs. A fundamental requirement of CAPTCHAs necessitates that they must be designed to be easy for humans but difficult for computers. However, it is well recognized that the trade-off between usability and security is difficult to balance. In addition, numerous attacks have been developed to defeat CAPTCHAs. In response to this, many different CAPTCHA design variants have been proposed over the years. Despite the fact that CAPTCHAs have been around for more than two decades, the future of CAPTCHAs remains an open question. This chapter presents an overview of research examining a wide range of issues that have been conducted on different types of CAPTCHAs.
