About the Game
Portal is Valve's first-person puzzle game, where you open portals to move through a mysterious science lab.
Portal is a single-player puzzle game from Valve that sits in the Action genre on Steam, with tags for Puzzle, First-Person, Sci-fi and Singleplayer. The store description calls it Valve's new single-player game and sets it in the mysterious Aperture Science lab, which it describes as one of the most creative new games around. That combination of a first-person view, a sci-fi setting and puzzle-focused tags gives you a clear sense of what to expect before you start.
The core loop revolves around opening portals. According to the store description, you move objects and yourself by opening portals, and you use this to work through puzzles and challenges. The game is designed to change how you handle, manipulate and guess at the possibilities within a fixed environment. The description compares this to using the Half-Life 2 gravity gun in any given situation, so each room tends to reward careful observation and experimentation rather than brute force.
What stands out is the emphasis on rethinking a space you already know. The store text promises several hours of a unique play experience, and the single-player focus means you move at your own pace while testing what your portals can do. If you enjoy puzzles that ask you to see the environment differently, the premise is clearly built around that idea.

Who It Is (and Is Not) For
Recommended For
Puzzle fans who enjoy experimenting with an environment to find a solution will likely find Portal rewarding. It also suits players who prefer a single-player, first-person experience with a sci-fi tone and want to play at their own pace.
Not Recommended For
Players who want fast multiplayer action will find nothing of that kind here, since the game is tagged Singleplayer. Anyone looking for a sprawling open-world adventure should look elsewhere, because the store description focuses on a lab-based puzzle experience lasting several hours.
What the Steam Reviews Say
Portal carries the Steam label Overwhelmingly Positive, which is 壓倒性好評 in Steam Taiwan wording and the same label in English. It has a 98 percent positive rating backed by hundreds of thousands of reviews.
Steam calculates its review labels from the share of positive reviews and the total number of reviews, so a label like this reflects a very large sample of players who overwhelmingly recommend the game. A high percentage combined with a huge review count is generally a more dependable signal than the same score from a small group. Still, a review label describes how players felt about the game overall, so you should check the store page to decide whether the puzzle style suits you.

Latest recorded price: NT$198
A price chart appears here once we have recorded at least a week of prices with some variation.
All prices in this guide are Taiwan Steam store prices in NT$. Portal currently sells for NT$ 198, which is also its regular price, and there is no discount on the page right now.
In our record, NT$ 198 is both the lowest paid price and the highest price we have logged. The game has never been discounted in our record and has never been free to keep on any day we tracked, and we have no previous free-to-keep promotions on record for it.
Our price record is still short, so this verdict is tentative. Because the price has held steady at NT$ 198, there is no sale pattern to rely on yet. If you want the game now, you are paying the lowest price we have logged, while waiting makes sense only if you are willing to rely on wishlist notifications to catch any change.
