一筆書きで、47都道府県を描け。 「わたしの日本地図」は、記憶だけを頼りに都道府県の輪郭を一筆で描く、新感覚のお絵かき評価ゲームです。描いた形は実際の県境と照合され、県ごとに異なる評価軸でスコア化されます。 ■ 形がそのまま「県の運命」になる ・能登半島が短い → 金沢金箔・海の幸スコアが激減 ・下北半島を描き忘れる → マグロに逃げられる ・土佐湾の弓なりが甘い → カツオが不漁に 名産・地理にちなんだ評価軸が、あなたの手の震えを容赦なく採点します。 ■ 3段階のガイドモード ・激甘:なぞりガイドで地図を覚える ・ノーマル:隣県のうっすらシルエットだけ ・ハード:ガイドなし、記憶のみで挑戦 ■ 手描きの日本地図が完成していく 遊ぶほどに、自分の描いた(少し歪んだ)形で日本地図が埋まっていきます。47県コンプリートは最高のスクリーンショット映え。 ■ レーダーチャート・称号・共有カード 軸別スコアをレーダーで可視化。「地図帳の妖精」「半島どこ置いてきた」など、低スコアでも笑える称号が待っています。結果はSNSでシェア。 完全オフラインで遊べます。地図データは国土数値情報(国土交通省)由来、統計値は e-Stat 等を参照した推定・目安です。 ※アプリ内課金「全国制覇パック」で全47県の開放・広告除去・称号図鑑の全解放ができます。

Put one phone in the middle of the table. Everyone taps their own side. That's it: the whole family is playing. I'm a dad of two, ages 6 and 4. I made Primal Fun so my kids, my wife and I could play together on one phone. The rules take 3 seconds, so even my 4-year-old jumps right in. And yes, the kids beat me more often than I'd like to admit. ■ Rules in 3 seconds, rounds in 10 Tap when the color changes, pass the bomb, stop at exactly 7 seconds… no long explanations, just laughing together. For 2–6 players on a single phone. ■ 23 mini games across 5 senses · Reflex – Faster Than Light, Tap the Real One, Left? Right!, Pop! · Sense – Exactly 7s, Just That Far, Dead Center, Cut in Half, Metronome · Touch – In Step!, Push Out!, Mash!, Perfect Shape, Tightrope · Eye – Right Now!, Odd One Out, Number Hunt, What's Missing?, How Many? · Nerve – Pass It!, Don't Be Last, Shrinking Zone, One More? Every game tests something different, so the winner changes from game to game. ■ Like a real tournament Pick how many games to play, spin the random roulette or choose each game. Standings build up game by game, and the champion takes the podium! ■ Solo too Chase your personal best in every game with Solo Practice. ■ No ads · No subscription 7 games are free the moment you install. Unlock the other 16 with a single purchase, yours forever. No ads will ever pop up in front of your kids. Plays offline. After dinner, rainy weekends, waiting at a restaurant, holidays with grandparents: one phone is all you need.

Verdict

On price, review sentiment, in-app purchases and monetization model there is nothing between them.
