PartyAt

Offline party games for 1 to 100 players on a single phone

Game Branding & design: Sai Beppu

Only one person in the group needs the app — everyone else joins with no download and no account. It holds 15 games, from word and bluffing games to classic boards, plus a roulette and a dice tool: 17 in all.

A party game app for people who are already in the same room, played by passing a single smartphone around. The screen shows whose turn it is by name and icon, so the phone just moves to the next person as the game leads them through it. Because it needs no connection at all, it works in basements, on trains, and anywhere else without a signal. Player counts vary by game: the roulette and dice tools work for one, chess is for two, and bingo takes up to 100. It is free to start and available in 15 languages, including English and Japanese. Where Dokopa is built for playing remotely over a voice call, PartyAt is built for the moments everyone is together.

Dokopa

A party game collection playable anytime, anywhere — one phone per player

Game Branding & design: Sai Beppu

Everyone joins the same room from their own phone and plays through the game together. It holds 39 or more games including Word Wolf, werewolf, and unanimous-choice games.

It works for groups as small as 2 and as large as 111. Play side by side, or pair it with a LINE or Discord call to reach people who are somewhere else. Titles such as improv comedy prompts and drawing telephone keep being added and updated, and it is currently free with no in-app purchases.

Keikenchi

Record your travels across Japan's 47 prefectures as a score

Tool Planning & supervision: Todofuken-Shikuchoson website (uub.jp) / Renewal design: Asami Yamanaka

Rate how you know each prefecture on six levels — lived, stayed overnight, walked around, stopped over, passed through, never visited — and the total becomes your "Keikenchi" score.

Every level carries its own point value, and as you fill them in the map of Japan colors itself, showing at a glance where you have and have not been. Several maps can be kept at once, so a family can hold separate records, or one person can track a year at a time.

Word Wolf - Definitive Edition

A word-based social deduction game with 1,400+ prompts

Game Original rules: Susumu Kawasaki (Kawasaki Factory)

Everyone is handed a word, but one player's is slightly different from the rest. The game was devised by Susumu Kawasaki of the board game circle Kawasaki Factory, and this app is published with the creator's approval. You talk around the topic without saying your own word, and try to work out who is holding the odd one.

Over 1,400 prompts are included, across categories such as food, daily life, hobbies, and romance. A round runs about five minutes, which suits parties and idle waiting. A “conversation hint” button is there for anyone playing for the first time.

God of Walk

Turns everyday walks into adventures with random divine orders

Game Original game & supervision: Drosselmeyer's

The walking god tells you "where to go" and "what to do," and you walk accordingly. Over 2,000 combinations mean the destination and the task come out different every time.

This is the app version of the analog game “Mr. Drosselmeyer’s God of Walk.” It depends on no particular route or landmark, so an ordinary loop around your own neighborhood is enough to play. Available as a one-time purchase. Once on the stores and later removed, the app was rebuilt by Qdan and brought back.

Koo-Ron-Do

Auto-generates 1,900+ pointless debate topics

Game Original game & supervision: Drosselmeyer's

Opening and closing phrases combine into pointless things to argue about, one after another. There is no conclusion to reach and no right answer — the game only wants the talk to keep rolling.

This is the app version of the analog game “Mr. Drosselmeyer’s Koo-Ron-Do,” made in connection with a collaboration with TBS Radio’s “After 6 Junction 2.” It supports several players at once and is sold as a one-time purchase. Previously on the stores and then removed, it is now back — with this being its first release on Android.

God of Free Time

Randomly suggests 130+ missions to fill idle time

Game Original game & supervision: Drosselmeyer's

Orders arrive from the "God of Free Time," and you spend your empty hours doing whatever they say. There is nothing to achieve and nothing to score — the point is only to make a dull moment slightly better.

This is the app version of an analog game by Drosselmeyer’s, and the indoor counterpart to God of Walk. Because you only have to follow what arrives, it starts anywhere — a wait, a commute, a gap in the day. Available as a one-time purchase.

God of Wits

Auto-generates 20,000+ improv comedy prompts

Game Original game & supervision: Drosselmeyer's

Three tiers of words — upper, middle and lower — combine into questions that have no correct answer. All anyone can bring to them is their own sense of humour.

This is the app version of the analog game “Mr. Drosselmeyer’s God of Wits.” The questions were written in full cooperation with the Akihabara ogiri (comedy) cafe “Bokeruba.” It supports group play, which suits drinking parties, social gatherings, and live stream content. Available as a one-time purchase.
