Welcome To...: Solo Mode introduces a solo AI variant designed by Alexis Allard for fans of the original board game who want to play alone. The box contains a full‑color rulebook and eight extra cards – five AAA architect cards and three completed plan cards – that give the AI its personality. Gameplay mirrors the core "Welcome To..." experience: you zone suburban neighborhoods, fill bingo grids, and fulfill contracts, but now you must contend with an artificial opponent that selects actions simultaneously and tries to block your best combos. Everything is paper‑and‑pencil, so there are no plastic pieces to lose, just plenty of strategic depth and pattern‑building focus. A typical playtime is about 25 minutes, making it perfect for a quick solo session or a nightcap challenge. With a BGG weight of 2/5, the game is light on complexity, suitable for newcomers and seasoned players alike looking for a low‑stress experience. Components are straightforward: printed rules, the AI cards, and the base game’s material. If you enjoy city‑building, bingo‑style scoring, and testing your planning skills against a virtual rival, this expansion hits the spot. Players who prefer heavier tactical games or heavy player interaction might find the solo mode less compelling, but it still delivers a polished, complete solo experience for those who like to play solo.
