Evaluation

Black Hole Simulator launched on September 4, 2021 and has received a steady stream of updates since then — visual effect improvements in August and September 2021, a patch in February 2022, feature additions (interface optimization, background music, graphics quality options) in September 2024, and a bug fix on March 31, 2025. On October 11, 2024, the developer posted a direct statement that "Black Hole will grow" and confirmed they will "continue to optimize the game." That is the most recent development-status communication from the developer. Updates have been delivered as free patches with no DLC or season pass structure. The developer's stated intent to keep expanding the game, backed by a consistent update history running through March 31, 2025, indicates the game continues to receive active support. The last communication was March 31, 2025 — roughly 18 months before today's date (October 8, 2026). This is longer than the roughly 6–12 month gaps seen between prior updates, which pushes toward the edge of the historical pattern, but the developer's explicit October 2024 statement of intent to continue means the game has not been declared finished. No completion announcement has been made.

About this game

Many people are interested in Einstein's theory of relativity as I am, but its complicated mathematics keeps us out. This game provides us with an opportunity to intuitively experience the wonderful appearance of objects under general relativity.

In a world dominated by gravitation, all objects appear so symmetrical and elegant. Black holes are the most representative existence in this magnificent world.

Game features:
1. Simulate the appearance of the black hole as accurately as possible.
2. You can adjust the parameters to change the appearance of the black hole.
3. You can also add a star to observe the interaction between the black hole and the star.
4. There are multiple space background sky boxes.
----------------- Update -----------------
5. Fly into the black hole, see the cosmic ball.
