To truly understand the power of Gemini 2.5 Pro Upgrade, I put it through a series of challenging tests ranging from solving Rubik’s Cubes to building complex interactive web apps and games—all generated in a single HTML file or Python script. Below are detailed insights from each test, showcasing the model’s versatility and creativity.
Rubik’s Cube Solver: From 3×3 to 20×20
The Rubik’s Cube test is a classic measure of algorithmic reasoning and spatial understanding. Gemini 2.5 Pro had previously solved a 10×10 cube in one try, but the upgrade introduced a scramble button that generates scrambles faster, now scrambling a 20×20 cube in just 12 moves.
After scrambling the 20×20 cube, the model took some time but eventually solved it flawlessly, demonstrating incredible problem-solving ability. The interactive features such as zoom, rotation, and scramble controls make the experience seamless.
Interactive 3D Floating Island Simulation
One of the most impressive demonstrations was generating a dreamy, low-poly floating island with dynamic lighting and gentle animations—all contained in a single HTML file. The model completed the task in just 25 seconds, producing a visually appealing scene with floating clouds, adjustable lighting, and sliders to control sun intensity, ambient light, fog effects, island bobbing speed, and cloud speed.
This test highlights Gemini’s strength in building interactive web apps with user controls, offering a playground for creativity and customization.
Galton Board Physics Simulation
Gemini 2.5 Pro also handled a complex Galton board simulation using client-side JavaScript and the Matter.js physics engine. The simulation featured adjustable parameters such as drop interval, number of balls, bins, peg rows, peg radius, ball radius, bounciness, and gravity—all controlled through sliders.
While the initial version had a minor flaw—a missing hole in the top funnel preventing balls from dropping—it was quickly fixed with a simple prompt iteration. The simulation produced a bell curve distribution of balls, closely mimicking real-world physics.
Flight Simulator Using 3.js
Taking things further, Gemini 2.5 Pro wrote a complete flight simulator in a single HTML file with a third-person camera, basic airplane geometry, simple controls (W/D for turning, pitch control, spacebar to speed up, shift to slow down), and a textured ground plane populated with buildings.
The simulation allowed free flight around the environment, with functional speed controls and realistic shadows, providing a fun and interactive experience.
Enhanced Snake Game in Python with Pygame
For classic gaming fans, the upgrade produced a visually stunning and complex Python version of Snake using Pygame.
