Start with one exhausted intern clutching coffee and merge your way to a legend of a completely fictional parliament. Tap the campaign scene to collect donations. Combine two candidates of the same level and build a 20-stage roster. Your camp keeps producing donations and votes while you are away, with up to eight hours of offline rewards waiting when you return. Features โ€ข 20 candidate levels and expandable camp slots โ€ข Six campaign routes with distinct bonuses โ€ข Ten promotion checkpoints and 36 absurd news events โ€ข Three rotating daily operations, a seven-day attendance track, and achievements โ€ข Five endings plus permanent bonuses through political reshuffles Optional in-app purchases provide game cash for the item draw; every itemโ€™s odds are shown before a draw. Ads are optional and reward-based; they never block the basic game loop. Every person, party, institution, and event in this game is fictional. Any resemblance is coincidental.
