《所羅門之鑰》（ソロモンの鍵，Soromon no Kagi/ Solomon's Key）是一款由Tecmo公司在1986年推出的益智類遊戲，最初發佈在任天堂紅白機跟街機。此遊戲後來還推出海外版本和續作，在PC Engine上移植時改名為《Zipang》。其他發行平台包括Commondore 64、FDS、Game Boy、Master System、3DS以及Wii U Virtual Console。

故事講述在遠古時代，所羅門王成功使用傳說中的「所羅門之鑰」的魔力，將所有可怕的魔鬼封印在星座宮的地底深處，和平再次的降臨。然而，多年後一位法師尋找神秘的星座宮，卻不慎解封了先前被囚禁的魔鬼，使世界再次陷入混亂。

為了解救世界，妖精園的紫丁香王尤特拉命令年輕魔法師達那前往12星座宮。這座宮殿由64個房間組成，每個房間之間都有門扉，只有取得鑰匙才能前進到下一個房間。避免達那免受邪惡魔力的傷害，精靈們在成功通過房間後，會施放光圈護送他到下一個目的地，並將他們的生命力轉化為玩家的得分。

遊戲中，紅白機版本共有64個關卡，包括15個隱藏舞台和最後的所羅門房間。48個關卡分為四個群組，基於黃道上的12個星座，如牡羊座、金牛座、雙子座、巨蠍座、獅子座、處女座、天秤座、天蠍座、射手座、魔羯座、水瓶座和雙魚座等。

每個星座都有一個神祕的獎勵房間，只有在通過該星座的最後一個房間時才能進入。這些房間中隱藏著精靈鐘、藍鑽石、橘色鑽石、橘色沙漏和二分之一的灰色瓶等道具。其他三個特殊關卡分別是「空間之房」、「時間之房」和「公主之間」，最終是「所羅門房間」。進入所羅門房間後，會失去所有火球，並需要巧妙地通過一系列挑戰才能破解所羅門之鑰，抵達到終點。遊戲還隱藏著八個所羅門封印，只有全部收集才能獲得最佳結局。

在遊戲中，當看到變化寶石時，可以使用魔仗切換所需的物品。當看到高級變化寶石時，會拿到效果更為強大的物品。獲得藍色火球瓶後，可以將其置入法術捲軸中，隨時使用。而橘色火球瓶的威力則更強大。收集到捲軸羊皮紙後，可以增加火球法術的儲存量，最多可達八個。藍色寶石可以擴大火球的傳播範圍，延伸一個方塊的距離。

橘色寶石則會增加兩個方塊的攻擊距離。取得橘色瓶子後，畫面上的所有敵人都將被消滅，並轉化為寶藏。藍色火球瓶中間有橘色彩帶標誌，取得後會讓原本的火球升級為超級火球。

在遊戲中，當拿到標示有E字體的瓶子時，可以增加一台數。另外，拿到橘色的沙漏會讓時間回到原本的一半，但如果過早收集則可能產生負面影響。另一方面，藍色沙漏則會將計時器調整回原有時間，建議在時間即將耗盡時再取得比較好。

半瓶的灰色酒瓶會讓剩下的時間內獎金加倍，但同時時間的減少速度也會倍增。而整罐的灰色酒瓶則會大幅增加獎金，但計時的流失速度會提高五倍。

在這款被公認為難度極高的紅白機遊戲中，玩家需要通過各種複雜的關卡，獲得鑰匙後進到下一個舞台。使用方向鍵進行上、下、左、右的移動，按上即可進行跳躍。按A創造方塊，再按一次即可破壞。按A或兩次頭敲可以破壞已存在的方塊，破壞方塊或使用火焰魔法都能造成敵人死亡。按B則施展火焰魔法。關卡中有顯性和隱性的道具，拿到將有利於後續進行。若未能在有限的時間內移動到下個舞台或與敵人碰觸，將失去一條生命。

當遊戲結束時，會顯示評分，評分標準包括通過的關卡、找到的物品和使用的時間等。在這個畫面出現時，按上+A+B，可在第41關或更早的舞台重新開始。而在第42關或更後面的關卡重新挑戰失敗時，將會從第41關重新開始。

結局會根據玩家完成的程度而略有不同，至少有三種結局，包括只有主角跑出地窟、主角跑出地窟後精靈們也飛出地窟，以及主角跑出地窟後精靈們也飛出地窟，最後所有魔物都被收回地窟。

挑戰的困難度極高，主要是因為設計非常複雜。要消滅敵人的方法相當有限，主要仰賴正確的策略。舞台還隱藏難以找到的物品和關卡，雖然可以激勵玩家，但也大幅增加挑戰性。

"Solomon's Key" (ソロモンの鍵, Soromon no Kagi/Solomon's Key) is a puzzle video game released by Tecmo in 1986. It was initially launched on the Nintendo Entertainment System (NES) and arcade. The game later saw overseas versions and sequels, with the PC Engine port being named "Zipang." Other platforms for release include the Commodore 64, FDS, Game Boy, Master System, 3DS, and Wii U Virtual Console.

The story unfolds in ancient times when King Solomon successfully used the magical power of the legendary "Solomon's Key" to seal all terrifying demons beneath the constellations' palace, bringing peace to the world once again. However, many years later, a wizard seeking the mysterious constellation palace accidentally unseals the previously imprisoned demons, plunging the world into chaos once more.

To save the world, King of the Fairy Garden commands the young wizard Dana to journey to the 12 Constellation Palaces. The palace consists of 64 rooms, each connected by doors that can only be opened with keys. To protect Dana from the evil magic, fairies cast a protective aura after successfully passing through a room, escorting him to the next destination and converting their life force into the player's score.

The game features a total of 64 levels on the NES, including 15 hidden stages and the final Solomon's Room. The 48 levels are divided into four groups based on the 12 zodiac signs, such as Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces.

Each zodiac sign has a mysterious bonus room accessible only after completing the final room of that sign. These rooms hide items like Fairy Bells, Blue Diamonds, Orange Diamonds, Orange Hourglasses, and Half-Grey Bottles. The three special levels are "Room of Space," "Room of Time," and "Room of Princess," culminating in the "Solomon's Room." Upon entering Solomon's Room, all fireballs are lost, and players must cleverly navigate a series of challenges to unlock Solomon's Key and reach the goal. The game also conceals eight Solomon Seals, requiring collection for the best ending.

Throughout the game, when encountering Change Jewels, players can use the Magic Staff to switch between desired items. Advanced Change Jewels grant more powerful effects. Upon obtaining a Blue Fireball Bottle, it can be placed in the spell scroll for later use. The Orange Fireball Bottle has even greater power. Collecting Parchment Sheepskin increases the storage capacity of fireball spells, up to a maximum of eight. Blue Gems enlarge the fireball's spread range by one square.

Orange Gems increase the attack range by two squares. Acquiring an Orange Bottle eliminates all enemies on the screen, transforming them into treasures. The Blue Fireball Bottle with an orange ribbon icon upgrades the regular fireball to a super fireball.

In the game, obtaining a bottle with the letter "E" font increases the score by one digit. Collecting an Orange Hourglass halves the remaining time, but it may have negative effects if collected too early. On the other hand, a Blue Hourglass resets the timer to its original duration, recommended for use when time is running out.

A Half-Grey Bottle doubles the bonus within the remaining time but accelerates the time depletion rate. A full Grey Bottle significantly increases the bonus but multiplies the time loss rate by five.

In this notoriously challenging NES game, players must navigate through various intricate levels, obtain keys, and progress to the next stage. Directional keys are used for movement (up, down, left, right), with the jump function activated by pressing up. Pressing A creates a block, and pressing it again destroys the block. Pressing A or two headbutts destroy existing blocks or use flame magic to defeat enemies. Pressing B activates flame magic.

Levels contain both explicit and hidden items beneficial for later stages. Failure to move to the next stage within a limited time or touching an enemy results in the loss of a life.

Upon completing the game, a score is displayed, evaluating factors such as cleared levels, found items, and time used. When this screen appears, pressing up+A+B allows players to restart from stage 41 or earlier. Restarting from stage 41 or later stages after failing a challenge in stage 42 or beyond will begin from stage 41.

Endings vary based on the player's completion level, with at least three possible outcomes. These include the protagonist escaping the dungeon, the protagonist and fairies flying out of the dungeon, and all monsters being resealed in the dungeon after the protagonist's escape.

The game's extreme difficulty stems from its intricate design. Limited methods exist to eliminate enemies, relying heavily on correct strategies. The stages hide challenging-to-find items and levels, motivating players but significantly increasing the overall difficulty.
