Squid game bridge diagram 4

Stick figures labelled 9, 10, 11 are to the right of a diagram of the bridge. On each coloumn, on square of the bridge is replaced by a Red Cross

Consider the player 𝑛 > 𝐿. At most, 𝐿 players fall to their death. This happens only if, as above, all of the first 𝐿 players choose to hop onto a weak glass panel in their first hop onto an unvisited column. This outcome would reveal the path for safe traversal over the bridge for the remaining 𝑁 − 𝐿 players behind them. Therefore, player 𝑛 is guaranteed to survive and 𝑃(𝐹𝑛) = 𝟢 for 𝑛 > 𝐿.
