One clean mechanic, enough.
The #17 slot.
Slot #17 of 27 in the Big Brother Editor's Canon. Seventeenth, the last of the modern-era run before the canon turns to seasons defined more by concept than by house dynamics. The Hacker Summer knows exactly what it is — one clean mechanic, one hardened alliance split — which is enough to edge out the twist-stacked seasons below it, A Summer of Mystery and Houseguests vs. the AI, but not enough to climb past the mythology-heavy seasons above it. The distinction between this slot and the next one down is instructive: a twist administered by a competition the houseguests actually play still ranks ahead of a twist administered by a theme controlling the season from outside the room.
