又是一年ggj，这次solo开发了一个个人玩的爆炸21点游戏！在把牌都爆光前，你能赚到多少钱呢？如果不爽，按空格还能砸桌子！

游戏说明：

• 牌桌分为两个区域：待选区和倍率区

  1. 待选区：1×4区域，共4个卡槽。

  2. 倍率区：每个卡槽提供基础倍率+1。当倍率区的横竖卡槽分别凑齐2个和3个相同花色时，提供乘数倍率×2／×3。
     总倍率 = 基础倍率 × 乘数倍率
     资金 = 所有花色的赢牌点数相加 × 总倍率。

爆牌点数范围： 当场上相同花色的点数和 > 21 时，视为该花色爆牌。
赢牌点数范围： 当场上相同花色的点数和 ≥ 17 且 ≤ 21 时，视为该花色赢牌。
无事发生点数范围： 当场上相同花色的点数和 ≥ 17 且 ≤ 21 时，视为该花色无事发生。

卡牌种类：

• A 2 3 4 5 6 7 8 9 10：对应点数1-10，每种花色各2张，共80张。

• J Q K：对应点数10，每种花色各2张，共24张。

• Black Joker：点击翻开时，撕掉所有倍率区的牌，共2张。

• Red Joker：点击翻开时，翻开所有场上的牌并撕掉，共2张。

• ♠/♥/♣/♦杀手：撕掉场上所有对应花色的牌，每种花色各1张，共4张。

• 反转牌：所有区域生效，爆牌点数范围和无事发生点数范围互换，共2张。

• 24牌：所有区域生效，爆牌点数变为24，共2张。

• 倍率牌：倍率区生效，基础倍率+1，生效后被撕毁，共2张。

• 防爆牌：倍率区生效，防止一次爆牌，生效后被撕毁，共2张。

游戏机制：

每轮开始时会抽四张牌，并背面朝上，放置在待选区。玩家可以点击翻开牌并扣除对应点数的资金，翻开的牌可以放置到倍率区。点击结算后，开始结算场上点数，并获取赢牌的资金和失去爆牌的资金。所有被视为爆牌的牌会被撕掉，剩余的牌保留。撕掉的牌永久消失。结算完成后可以开始下一轮。游戏继续进行，直到玩家亏掉所有资金或所有牌被爆光。

It's another year of GGJ, and this time I developed a solo project: Booming 21, a solo "explosive 21" game! How much can you earn before you explode all the cards? If you get frustrated, hit the spacebar to slam the table!

Game Overview:

• The table is divided into two areas: Selection Area and Multiplier Area

  1. Selection Area: A 1x4 grid with 4 slots.

  2. Multiplier Area: Each slot provides a base multiplier of +1. When the horizontal and vertical slots in the multiplier area each contain 2 and 3 matching suits, they provide multiplier bonuses of ×2 and ×3.
     Total multiplier = Base multiplier × Suit multiplier
     Funds = Total winning points of all suits × Total multiplier.

Explosion Points Range: When the sum of points for a suit exceeds 21, it is considered an explosion.
Winning Points Range: When the sum of points for a suit is between 17 and 21, it is considered a winning suit.
No Event Points Range: When the sum of points for a suit is between 17 and 21, but not exceeding 21, it is considered a neutral event.

Card Types:

• A 2 3 4 5 6 7 8 9 10: Corresponding points 1-10, two cards of each suit, totaling 80 cards.

• J Q K: Corresponding points 10, two cards of each suit, totaling 24 cards.

• Black Joker: When clicked, destroys all cards in the multiplier area, 2 cards in total.

• Red Joker: When clicked, reveals all cards on the table and destroys them, 2 cards in total.

• ♠/♥/♣/♦ Killer: Destroys all cards of the corresponding suit on the table, 1 card of each suit, totaling 4 cards.

• Reverse Card: Affects all areas, swapping explosion and no-event points ranges, 2 cards in total.

• 24 Card: Affects all areas, setting explosion points to 24, 2 cards in total.

• Multiplier Card: Affects the multiplier area, increasing the base multiplier by +1, discarded after use, 2 cards in total.

• Anti-Explosion Card: Affects the multiplier area, preventing one explosion, discarded after use, 2 cards in total.

Game Mechanics:

Each round starts with four cards drawn and placed face-down in the selection area. Players can click to reveal the cards, deducting funds equal to the card points. Revealed cards can be placed into the multiplier area. When players hit "settle," the points are calculated, and they earn funds based on the winning points, while losing funds for explosion points. Any cards considered exploded are discarded, while the remaining cards stay in play. Discarded cards are permanently removed from the game. Once the settlement is complete, the next round begins. The game continues until the player runs out of funds or all the cards are revealed.
