The text provided does not contain a hidden grid or a list of words to find, which are typically part of a word search puzzle. Instead, it describes features and updates of a word search game. If you are looking for a secret word or hidden words within the text itself, here is a step-by-step approach to identify potential hidden words:

1. Identify Key Phrases: Look for phrases that might hint at hidden words or a secret word. Phrases like "Find all the secret words" and "With the remaining letters" suggest that the game involves finding secret words using remaining letters after finding the main words.

2. Analyze the Text: Go through the text to see if any words or letters stand out. Since there's no actual grid, consider if any words are repeated or emphasized.

3. Focus on Unique Elements: Pay attention to any unique formatting or symbols, such as the stars (★) which highlight key features of the game.

4. Consider the Context: The text mentions "secret words" and "remaining letters," which implies that in the actual game, after finding all listed words, players use the remaining letters to form a secret word.

Given the text's nature, there is no direct secret word hidden within it. However, based on the game's description, the secret word would typically be found by using the remaining letters after solving the word search puzzle within the game itself.

If you're looking for a specific word or phrase from the text that might be considered "secret," you could focus on unique or less common words. However, none stand out as overtly hidden or secret within the provided text.

If you have an actual word search puzzle grid or a different context where a secret word is hidden, please provide that for a more accurate analysis.
