πに聞け!— 戦略ゼロ、運だけの円周率バトル。 二人がそれぞれ数字を入力。その数字が円周率(π)40万桁の中で何桁目に出現するかを調べ、勝敗を判定する対戦ゲームです。 考えても無駄。選んでも無意味。すべてはπが決める。 【遊び方】 ラウンド数を選んで対戦開始(3 / 5 / 7ラウンド) 毎ラウンド、桁数と勝利条件がランダムで決定 Player 1とPlayer 2が交互に数字を入力 πの中からその数字を探索 出現位置で勝敗が決まる 【勝利条件(ランダム)】 ・遠い方が勝ち — πの奥深くで見つかった方の勝ち ・近い方が勝ち — πの入口に近い方の勝ち ・ターゲットマッチ — ランダムな目標桁に近い方の勝ち 【必殺技(P2専用)】 ・書き換え — 相手の数字を1桁変更 ・のぞき見 — 相手の数字を2.5秒だけ確認 ・条件反転 — 勝利条件を真逆にする 【特徴】 ・π(円周率)40万桁を内蔵 ・美しいノート風デザイン ・無意味な統計ダッシュボード付き ・戦略は存在しません

Verdict
The clearest difference is ads: πに聞け! at none against ONE HALF's shown. πに聞け! also leads on iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
