The Best Resources for Your Idea

Felgo offers various tutorials and demo games for most common game genres.

Games where players play against each other using cards.

Card Game
like UNO, Hearthstone or Poker

In match-3 (tile-matching) games the player manipulates tiles in order to make them disappear according to a matching criterion, like 3 tiles of the same type. The core challenge of tile-matching games is the identification of patterns on a seemingly chaotic board.

like Candy Crush Saga

Puzzle is a highly extensible term, which can refer to all kinds of "use your brain (or some luck?) to solve something" type of game.

like 2048 or Threes!

Felgo also offers components for casino games, slot games in particular. Spin to win!

like Big Win Slots

Games where the level automatically scrolls in one direction and the player has to pass the incoming obstacles, collect objects, etc.

Side Scroller
like Jetpack Joyride or Flappy Bird

The goal of tower defense games is to try to stop the enemies from reaching a specific point on the map by building a variety of different towers which shoot at them as they pass.

Tower Defense
like Castle Defense or Bloons TD

The player uses platforms or similar to progress through the level, either upwards (Jump) or downwards (Falldown). Missing the platforms can quickly lead to losing the game. The level can either scroll constantly, or follow the player, but usually only in the "positive" direction.

Falldown & Jump
like Doodle Jump or Mega Jump

Jump'n'run games where you try to defeat enemies and reach the end of the level. Unlike the Side Scrollers, the level does not scroll automatically in one direction but you control in which direction you are moving.

like Super Mario or Lep's World

Games which require fast thinking paired with good reaction times. Most often action games are physics-based.

like Angry Birds, Fruit Ninja, Cut the Rope

Old but Gold, those timeless classics could use a revive, what are you waiting for?

like Arkanoid or Space Invaders

Tired of creating countless levels to keep your players attracted to your game? Why not let your players do this for you? Reward them for their effort, let them create a living community by themselves.

like Super Mario Maker or Minecraft

Making a game with Felgo saves you so much time, because you can add Particle-effects, animations and a level editor very easily. Thanks to great support of Felgo(answering questions within hours, applying hotfixes within one day) it was a real pleasure to make a game and fill it with lots of content. Because of these reasons we could create a prototype within a few days and we were able to polish the game, so that we could release it after only one month. Christian Bartsch
