《神魔之塔》（Tower of Saviors）是由香港遊戲開發公司Mad Head Limited於2013年1月推出的益智消除類手機遊戲。融合傳統的三消玩法和角色扮演遊戲（RPG）元素，並以其豐富的故事背景和多元的玩法迅速在華語地區取得巨大成功。主要在iOS和Android平台上運行，並且至今仍保持著定期更新和龐大的玩家群體。

基於經典的「三消」機制，需要在限定的回合數內移動和連接相同顏色的符石來達成消除效果。每消除一組符石，就能對敵人造成攻擊或觸發特定的角色技能。與其他三消類遊戲不同的是，在遊戲中操控的不僅僅是符石的消除，還有來自各種神話、歷史或原創背景的角色，這些角色被稱為「召喚獸」。需要組建自己的隊伍，並利用召喚獸的能力來過關斬將。

故事背景融合多種文化和神話元素，從希臘、埃及、北歐到中國的傳說，都成為遊戲的素材來源。古代人類建造能通向天界的以諾塔為主題，敘述在建造塔的過程中，惡魔試圖利用以諾塔入侵天界的故事。玩家作為召喚師，肩負著解開召喚獸封印的責任，一步步登上塔頂，尋求神的協助。

操作上，通過滑動手指來移動符石，達到連續消除的效果並利用我方召喚獸隊伍的力量向敵人發動攻擊。符石有六種不同屬性（火、水、木、光、暗、心），每一種屬性對應不同的召喚獸。消除相應顏色的符石，會讓對應屬性的召喚獸進行攻擊或發動技能。此外，召喚獸還可以通過累積特定條件來釋放技能，例如治療、強化隊伍、削弱敵人等。這使得遊戲的策略性很強，不僅要在限定時間內快速消除符石，還要根據隊伍的技能搭配做出最佳決策。

《神魔之塔》不僅能夠培養玩家高超的轉珠技能，還需要運用智慧，分析每隻召喚獸的獨特技能，從而組合出一支最善戰、最具攻擊力的隊伍。官方表示：「遊戲中的召喚獸以歐美畫風為主，精緻的畫風充分展現290隻以上召喚獸的氣勢和性格。此外，團隊選用Unity引擎加入3D特效，在戰場上，享受到技能配合特效的視覺盛宴。」

遊戲中有多種關卡和挑戰，分為主線故事關卡、每日挑戰、聯盟戰鬥以及限時活動等。主線故事是遊戲的核心內容，伴隨著劇情的推進，需要挑戰逐漸增強的敵人和首領。每個關卡通常由數個回合組成，必須在限制的步數或回合數內擊敗所有敵人。此外，《神魔之塔》定期推出限時活動關卡，這些關卡常常包含強大的BOSS或特殊的獎勵角色，吸引玩家反覆挑戰。遊戲的設計鼓勵玩家不斷優化隊伍配置，並學習如何在不同情境下使用最佳策略。隨著後期難度的提升，越來越考驗玩家的思考和反應能力。

《神魔之塔》的優點之一在於其融合三消和RPG兩大類型的優勢，這種創新性的玩法吸引大量的玩家。符石消除系統使其比一般的RPG更加具有動感，同時，召喚獸的收集和培養又讓遊戲充滿長期的遊玩動力。不同召喚獸之間的搭配，以及各類技能的策略性使用，也讓遊戲具有很高的重玩價值。其次，定期不斷加入新的角色、劇情和活動，維持玩家的興趣。還經常與其他知名作品進行聯動合作，比如與《七龍珠》、《進擊的巨人》等熱門動漫進行合作活動，這大大提高遊戲的吸引力。

遊戲也有一些缺點。首先是整體的難度曲線較高，對新手玩家來說，某些關卡可能過於困難，導致挫折感。儘管有指引教學，但對於沒有消除類遊戲經驗的玩家來說，仍然需要一段時間適應。此外，儘管遊戲本身免費，但有一定的「課金」系統，要購買虛擬貨幣來加速角色的收集和培養，這使得在公平競技性上略顯不平衡，某些玩家可能覺得不課金難以追上進度。

《神魔之塔》在華語地區尤其是台灣和香港市場取得極大的成功，這主要歸功於它豐富的玩法和不斷更新的內容。在發佈後，迅速在iOS和Android排行榜上佔據高位，並多次獲得各類手機遊戲獎項。在玩家社群中，它被視為一款極具挑戰性和深度的益智遊戲，吸引大量熱衷於解謎和策略的玩家。隨著其他競爭性遊戲的崛起，例如《龍族拼圖/智龍迷城》（Puzzle & Dragons）等，《神魔之塔》的市場占有率在後期略有下滑。儘管如此，Mad Head Limited透過不斷推出聯動活動、改善遊戲體驗，以及增加新的故事篇章，成功保持忠實玩家群體的興趣。對於遊戲評價，市場普遍認為其在創意和遊玩性方面非常出色，但由於後期難度較高，且長期玩可能會出現重複感，對某些玩家來說耐玩度有限。

總體來說，這是一款成功的創新手機遊戲，儘管它面臨著來自其他遊戲的競爭，但依然在益智遊戲領域中佔有一席之地。內容豐富性和深度為其贏得不小的市場佔有率和忠實玩家群體，儘管其課金系統和高難度設計可能讓部分玩家感到挫敗。

Tower of Saviors is a puzzle-based mobile game developed by the Hong Kong gaming company Mad Head Limited, first released in January 2013. It combines traditional match-three gameplay with role-playing game (RPG) elements. With its rich storyline and diverse gameplay, it quickly gained immense popularity in Chinese-speaking regions. The game runs on iOS and Android platforms and continues to receive regular updates, maintaining a large and dedicated player base.

The core gameplay is based on the classic "match-three" mechanism, where players must move and connect similarly colored runestones within a limited number of turns to achieve combos. Each successful match triggers an attack or activates a specific character skill. Unlike other match-three games, Tower of Saviors adds an extra layer of depth by allowing players to control various characters called "summoners," derived from mythology, history, or original stories. Players must build a team and use their summoners' abilities to defeat enemies and progress through the game.

The story integrates elements from various mythologies and cultural legends, drawing from Greek, Egyptian, Norse, and Chinese folklore. The central plot revolves around the construction of the Enochian Tower, which was built by ancient humans to reach the heavens. As the tower rises, demons attempt to invade the heavens, using the structure as a bridge. Players, acting as summoners, are tasked with unlocking the seals of these mythical creatures and ascending the tower to seek divine assistance.

Players swipe their fingers to move the runestones and create combos to activate their team's attacks. There are six different types of runestones: Fire, Water, Wood, Light, Dark, and Heart, each corresponding to specific summoners. Matching the corresponding color runestones allows the associated summoner to attack or use a skill. Summoners can also unleash special abilities, such as healing, enhancing team power, or weakening enemies, by accumulating certain conditions during the game. This strategic layer makes the game complex, requiring not only fast combo creation but also thoughtful use of team skills.

Tower of Saviors trains players in mastering puzzle-solving techniques while also encouraging them to use strategy. Summoners' unique abilities must be combined to form the most powerful team possible. The official team behind the game has said, "The summoners are designed with a Western art style, with over 290 different characters that showcase their power and personality. Additionally, the game uses the Unity engine to add 3D effects, creating a visual feast when skills are activated."

The game features a variety of challenges and levels, including story-driven stages, daily challenges, alliance battles, and time-limited events. The main storyline forms the core of the game, with players advancing through increasingly difficult battles and bosses. Each stage typically consists of several rounds, and players must defeat all enemies within the limited number of moves or turns.

Tower of Saviors also frequently introduces limited-time event stages, often featuring powerful bosses or special reward characters, motivating players to replay levels for higher rewards. The game's design encourages players to continuously optimize their teams and learn how to employ the best strategies in different situations. As the game progresses, it increasingly tests the player's problem-solving and reaction skills.

One of the game's strengths is its fusion of match-three mechanics with RPG elements, a creative combination that has attracted a large player base. The matching system makes the game more dynamic than typical RPGs, while the collection and cultivation of summoners provide long-term motivation for players. The strategic use of skills and synergies between different summoners adds depth and replayability to the game.

Another strength is the consistent introduction of new characters, storylines, and events, keeping players engaged. The game often collaborates with other popular franchises, such as Dragon Ball and Attack on Titan, to run collaborative events, further enhancing its appeal.

However, the game also has its drawbacks. The overall difficulty curve can be steep, and some stages may be too challenging for new players, leading to frustration. Although there are tutorials, players without prior experience in puzzle games may find the learning curve steep. Additionally, while the game is free to play, it includes a microtransaction system, allowing players to purchase virtual currency to accelerate character collection and development. This can create a sense of imbalance in competitive play, as some players may feel that they need to spend money to keep up with others.

Tower of Saviors has achieved great success, particularly in markets like Taiwan and Hong Kong, thanks to its engaging gameplay and continuous updates. Upon release, it quickly rose to the top of both iOS and Android rankings and has won several mobile game awards. Among player communities, it is regarded as a highly challenging and in-depth puzzle game, appealing to players who enjoy puzzle-solving and strategy.

Despite facing competition from games like Puzzle & Dragons, Tower of Saviors maintained its player base by consistently releasing new content, improving the gameplay experience, and introducing new story arcs. While the game’s creative gameplay and rich content have been praised, its difficulty and repetition over time may limit its long-term appeal for some players.

Overall, Tower of Saviors is a successful and innovative mobile game. Despite competition from other titles, it remains a prominent figure in the puzzle game genre. Its extensive content and depth have earned it a significant market share and a loyal player community, though its microtransaction system and challenging difficulty might deter some players.
