If by arranging the letters of the word LASBEBLA, the name of a game is…

Concept: In a letter-rearrangement (anagram) question, every letter of the given jumbled word must be used exactly once — none added, dropped, or repeated beyond what is already present — to spell a valid, meaningful word. Solving it means finding the word whose exact letter-set matches the jumbled word, then reading off that word's first and last letters.

Application:

1. List the letters of LASBEBLA and count each one: A appears twice, B appears twice, E appears once, L appears twice, and S appears once — eight letters in total.

2. Look for a well-known game or sport name that can be built from exactly these eight letters, using each letter the same number of times.

3. The sport name BASEBALL uses B twice, A twice, S once, E once, and L twice — the very same eight letters, just in a different order.

4. So rearranging the letters of LASBEBLA gives the game name BASEBALL.

Cross-check: Tallying BASEBALL's own letters — B, A, S, E, B, A, L, L — gives A=2, B=2, E=1, L=2, S=1, exactly matching the letters of LASBEBLA, confirming every letter is used once with none left over or invented.

Answer: The first letter of the game name formed is B and the last letter is L.
