🌟 Introduction

Get ready to be amazed by StackRabbit, an AI developed by the author that plays Tetris! This AI has been extensively worked on for months, resulting in some mind-blowing achievements. In this article, we will dive into the capabilities of StackRabbit and explore its gameplay strategies. Let's jump right in!

🏆 StackRabbit AI Achievements

StackRabbit has impressed the gaming community with its remarkable achievements. By limiting its capabilities to match human limitations, it has reached astonishing levels of success. Not only has it surpassed the human world Record of 1.439 million points, but it has also achieved million-point scores without even reaching the killscreen. StackRabbit has proven itself to be a formidable Tetris player.

🏃 Game Speed and Human Limitations

StackRabbit operates at a frequency of 13.5 taps per Second, which is lower than that of top players who set world records. This deliberate limitation, along with a reaction time of 416 milliseconds, creates a gameplay speed that emulates human capabilities. While it may seem fast for an AI, it still falls within the realm of possibility for skilled human players.

🎮 Gameplay and Adjustments

One of the most impressive aspects of StackRabbit's gameplay is its ability to make precise placements and adjustments based on the upcoming piece. By strategically setting up overhangs that fit perfectly with the next piece, StackRabbit optimizes its resulting stack. This adaptive gameplay showcases the AI's advanced decision-making capabilities.

💡 How StackRabbit AI Works

StackRabbit operates by reading the board and conducting move searches up to three moves into the future. It takes into account the features of the next piece and different possible pieces it can receive. To improve efficiency, StackRabbit prunes certain future scenarios that it deems unreasonable. Additionally, a sophisticated evaluation function assesses the quality of the board based on various principles, including research and statistical testing.

🔍 Evaluating Board Quality

StackRabbit's evaluation function analyzes the worth of different board surfaces. By focusing on attributes such as the absence of holes, Height, and Shape, it gains valuable insights into how the pieces will fit together. The AI benefits greatly from a rating system contributed by another Tetris player, Fractal. This rating system analyzes the shape of the top of the board, providing StackRabbit with a holistic view of the board's potential.

⚔️ Killscreen Strategy

As gameplay progresses, reaching the killscreen becomes a challenge for both humans and AI. At level 29, the game's speed increases dramatically, necessitating a change in stacking techniques. StackRabbit explores different stacking methods for the killscreen, particularly focusing on building and maintaining the left side of the board. By strategically utilizing specific pieces and shapes, StackRabbit optimizes its gameplay for this challenging phase.

⚡ Level 18 Efficiency

Playing at level 18 requires maximizing efficiency to achieve optimal results. The goal is to clear Tetrises and minimize wasted line clears, as the number of available line clears diminishes before reaching the killscreen. StackRabbit employs strategies to accomplish this efficiently, ensuring the board can accommodate any incoming piece.

🔄 Level 19 Challenges

Level 19 introduces a significant speed increase, making gameplay more strenuous. The limited space on the left side of the board poses a significant challenge, as pieces cannot be easily placed there. StackRabbit must carefully manage its stack size and adapt its strategy based on its reaction time limitations. To overcome this challenge, StackRabbit must create a board that accommodates as many pieces as possible.

🔝 Max Out and Beyond

Traditionally, reaching the max-out score of 99999 was considered a significant achievement. However, the skills of Tetris players have evolved, pushing scores beyond this limit. StackRabbit's performance has already surpassed both the human world record and its personal best score. With human-like parameters, StackRabbit has achieved a score of e65, outperforming human players and setting new records in the game.

🔄 The Revolution of Button Pressing Speed

A recent revolution among gamers involves mastering incredibly fast button presses. This technique makes killscreen stacking seem trivial, as players can precisely place pieces where they desire. However, StackRabbit focuses on optimizing traditional gameplay, simulating manual piece tapping instead of relying on lightning-fast button presses.

⚖️ Traditional vs Fast Button Pressing

While fast button pressing may seem advantageous, StackRabbit's approach demonstrates the effectiveness of traditional gameplay techniques. By carefully analyzing its inputs and predicting outcomes, StackRabbit showcases its intelligence and strategic decision-making. Its success proves that traditional gameplay remains a viable and remarkable strategy.

💥 The Magic of Killscreen Play

StackRabbit's killscreen play is truly exceptional and unparalleled. With a deep understanding of the game mechanics, it navigates the challenging killscreen phase with finesse. By building specific shapes and making counter-intuitive moves, StackRabbit maximizes its chances of success. The combination of strategy, adaptability, and precise piece placement creates an extraordinary gameplay experience.

🎯 RNG and Strategic Building

The killscreen phase heavily relies on RNG (random number generation) and strategic building. StackRabbit often requires specific pieces to fill gaps at the side of the board, which heavily depends on luck. However, strategic planning and preemptive building can mitigate the impact of RNG. StackRabbit's ability to adapt to varying circumstances further demonstrates its high level of play.

🧱 Stabilizing and Scoring Tetris

One of the impressive aspects of StackRabbit's gameplay is its ability to stabilize the stack after securing a Tetris. Even after facing a dangerously high stack, the AI can adeptly maneuver and create a stable structure. This skill showcases StackRabbit's exceptional decision-making and adaptability, resulting in incredibly high scores.

🌟 Beyond Human World Records

StackRabbit's performance has shattered human world records, achieving scores that surpass what was once thought possible. While human players tap at speeds of 15-17 hertz, StackRabbit's accomplishment of surpassing the 1.5 million-point mark with a reaction time limitation is nothing short of extraordinary. It demonstrates the immense potential of AI-powered gameplay in the gaming world.

🚀 The Future of StackRabbit AI

The development of AI players in the Tetris community is an exciting frontier. StackRabbit sets the stage for future bot competitions and advancements in AI gameplay. Stay tuned for more thrilling updates and innovations in the world of Tetris AI.
