About this game
All You Have to Do Is Place Seals
Place magical Seals on mysterious creatures called Spirits to grant them a variety of powers.
Some Seals boost their attacks, while others activate under specific conditions.
Which Seal should you choose, and which Spirit should receive it?
The controls are simple, but every choice can have a major impact on the battle.
The power of a Seal doesn't last forever. Keep using it, and eventually its effect will fade.
Keep placing new Seals and adapt your combinations as you fight your way forward.
The Seal You Don't Choose Goes to the Enemy
Whenever you gain a new Seal, you're presented with two choices.
You can take only one—and the other goes to the enemy.
Do you take the Seal that makes you stronger?
Or deny the enemy a Seal you don't want them to have?
Every choice changes both your side and theirs.
Then Watch Your Spirits Fight
Once you've placed your Seals, a 2-on-2 turn-based auto battle begins.
You don't issue commands during combat.
Your Spirits fight on their own using the powers granted by the Seals you've given them.
Choose. Place. Watch.
Experiment with different Seal combinations and discover your own path to victory.

Seal of Magic – December 2025 Development Update
Development Update After extensive trial and error, the core gameplay has finally taken shape. Although development has continued into the new year, the overall design is now stable. From here on, I plan to pick up the pace and focus on bringing the game to completion. Shift to a Pure Auto-Battle System While experimenting with various ideas, the game naturally evolved into an auto-battler. At the start of a run, players choose two allies (Spirits) and strengthen them using Seals obtained after each battle to progress through encounters. Originally, players were meant to place Seals every turn during combat. However, this felt slow-paced and led to repetitive actions rather than meaningful decision-making. Consequently, I’ve shifted player decisions to a pre-battle preparation phase, making the battles themselves fully automated. Enemies Scale with Seals In this game, enemies are enhanced by Seals just like the player’s team. As you advance through Waves, enemy stats increase, and their Seals become more powerful and higher-level. Even the same enemy type will provide a different challenge depending on the Wave and its specific Seal configuration. Leveling Up Through Seal Placement I have introduced a leveling system based on Seal placement. Each Seal has an attribute; placing Seals of the same attribute adjacent to each other increases their level and boosts their effects. This adds a layer of strategy where not only which Seals you choose matters, but also where you place them. I am currently focusing on polishing these core systems. It will take a bit more time, but I want to deliver a version of the game that I can truly be satisfied with.Read full article on Community Announcements (Ankou)AnnouncementsOfficial
シールオブマジック 開発進捗20250510
ゲームのコア部分に関わる仕様の見直しを進めていました。 {STEAM_CLAN_IMAGE}/45600724/56457d02b400a4a397ac9058eaa45611d7cbd41c.png デッキ構築要素からパラメータ強化型に 当初はバトル中に新しいシールをピックしてデッキを構築するシステムを入れる予定でしたが、実際に試してみるとテンポが悪く、戦略的な面白さとも噛み合いませんでした。 そのため、思い切ってデッキ構築要素は外し、代わりに永続的な強化パラメータによるビルド要素を重視する方向にします。 シール解放の戦略性を拡張 敵に与えるダメージは、グリッド上に貼ったシールが溜めた「パワー」を解放することで発生します。シールはターンごとに自動で攻撃するのではなく、手動で解放してダメージを狙う設計に変更しました。 解放にはするためには専用カウントを溜め、いつ解放するかが戦略の鍵になります。 今後は、複数シールを同時に解放してコンボボーナスを得るなど、さらに奥行きのある仕組みも追加予定です。 引き続き、戦闘テンポと戦略性のバランスを取るために調整を進めていきます。Read full article on Community Announcements (Ankou)
