HTML5 Strategy Game Source Code

How to choose HTML5 strategy game source code

The strategy games above cover five styles: tower defense, turn-based hex strategy, a deckbuilding roguelite, a merge auto-battler and a survival resource game. All six are built on Phaser 4.2.1 and written in TypeScript, and all have a daily challenge, achievements and local saves. Strategy games live or die on balance, so the useful question is how easy each one is to tune, and how long a session lasts on the screens your players use.

Mechanics and who they suit

Tower defense. Pocket Tower Defense lets players move towers between lanes and combine elements, with bosses, challenge modifiers and tower mastery for replay value. Train Defense turns the base into a moving train: players mount and rearrange weapons on carriages while crossing enemy territory, with route choices and a steampunk look. Both suit portals with returning players who want short, replayable levels.

Turn-based strategy. Hex Kingdoms is a compact 4X-lite: expand across a hex map, gather resources, capture towns and outmaneuver AI kingdoms under fog of war. Skirmish mode on procedural maps keeps it playable after the campaign. It fits desktop players who like to think between turns.

Deckbuilding. Card Combo Rogue builds a temporary deck each run around tag synergies across fire, machine, nature, magic and poison cards. Enemy intents are shown in advance, a guided tutorial teaches the rules, and a run can be resumed at any time.

Auto-battle and survival. Merge Army Tactics is the only portrait strategy game here: merge identical units into stronger ones, arrange the formation, then watch the battle play out. That loop works well in short phone sessions. Island Survival Strategy has players assign a small group of survivors to gather food, build shelter, explore and defend an island, and it is tagged family-friendly.

Rebalancing without rewriting

In five of the six games, unit stats, waves, maps, scenarios or rules are JSON data files in the game's data/ folder. You can make a tower cheaper, an enemy wave tougher or a map smaller by editing data, then run the game's tests and rebuild. Card Combo Rogue keeps its cards, enemies and relics in TypeScript data modules instead, so adding a card means editing typed data and running the type checker. Within your license you can also rename the game and replace art; ASSETS.md lists where every asset comes from.
