In the following question about indoor and outdoor games, four games are listed: Cricket, Carrom, Table Tennis and Chess. Three of these games are typically played indoors on a board or table, while one is mainly played outdoors on a large ground. From the given alternatives, which game is the odd one out?

Introduction / Context:
This is a classification-based odd one out question from the general aptitude section. You are given four popular games: Cricket, Carrom, Table Tennis and Chess. While all of them are well known, they differ in where and how they are usually played. Your job is to identify which game does not belong with the other three in terms of being an indoor versus outdoor game.

Given Data / Assumptions:

• Games listed: Cricket, Carrom, Table Tennis, Chess.
• We assume their usual playing environment: indoor or outdoor.
• Carrom, Table Tennis and Chess are generally played indoors on a small surface.
• Cricket is mainly played outdoors on a larger ground.

Concept / Approach:
The concept here is to classify games based on their typical playing venue and equipment:

• Indoor games are usually played inside a room on tables or boards.
• Outdoor games generally require large open grounds or fields.

By identifying which game does not fit the indoor category, we can select the odd one out. This approach uses simple real-life knowledge rather than complex calculations.

Step-by-Step Solution:
Step 1: Consider Carrom. Carrom is a board game that is almost always played indoors on a carrom board placed on a table or stand. Step 2: Consider Table Tennis. Table Tennis is played on a table with a net in the middle and is typically played indoors in halls or sports rooms. Step 3: Consider Chess. Chess is a strategic board game that is played indoors on a chessboard placed on a table. Step 4: Note the commonality: Carrom, Table Tennis and Chess are all indoor games played on compact surfaces. Step 5: Consider Cricket. Cricket is normally played outdoors on a large ground or stadium, with a pitch in the centre and fielders spread out across the field. Step 6: Because Cricket clearly differs in its outdoor nature and large playing area, it is the odd one out among these games.

Verification / Alternative check:
Another way to verify is to imagine the equipment and venue required: Indoor board or table-based equipment: Carrom board, Table Tennis table, Chess board. Outdoor field and pitch-based equipment: Cricket bat, ball and large ground. Only Cricket demands a large outdoor field as an essential part of the game. This classification confirms that Cricket is different from the others.

Why Other Options Are Wrong:
Carrom is not odd because it is a typical indoor board game. Table Tennis is not odd because it is primarily played indoors on a table. Chess is not odd because it is also an indoor, table-top board game. Cricket alone is mainly an outdoor sport played on a field, making it the outlier.

Common Pitfalls:
Some students may think that Table Tennis can also be played outdoors, but standard competitive and organised Table Tennis is predominantly an indoor sport. Another pitfall is focusing on the popularity of the game instead of the place where it is played. For aptitude classification questions, always focus on the main defining characteristic, not side details.

Final Answer:
The game that is mainly outdoor and therefore the odd one out is Cricket.
