The most hours I 've spend on a paid game that costs less than 2$ is Kingdom Rush. I think it has now turned freemium so I would suggest the newer paid one Kingdom Rush Frontiers
5) Kingdom Rush Frontiers | $1.99 - Landscape
It’s almost impossible to talk about TDs without mentioning the highly influential and popular Kingdom Rush series.
The first game in this series actually released as a free Flash browser game on Armor Games back in 2011, but there are now no less than 4 games available on mobile.
The most popular is definitely the free first game, but it’s closely followed by the $1.99 USD premium game Kingdom Rush Frontiers, which has received really high scores across both Android and iOS.
The core gameplay in Kingdom Rush is very straightforward, with the biggest differentiator being that we can spawn a main hero that we can move around the map. But the neat fantasy theme, cute cartoony art-style, and highly polished gameplay and game design makes this an easy recommendation for anyone who hasn’t played it yet.
6) Broken Universe | Free - Landscape
Released just about a year ago, Broken Universe is the newest game of the pack, and it actually manages to set itself apart through a few twists to the typical gameplay formula.
It all starts with the option to select where we want our base to be placed in each level. From there, we then have the freedom to setup a maze of towers or just wall ourself in to attack the enemies head-on instead.
The enemy design is also really interesting in Broken Universe, with everything from self-destructing monsters to bosses with unique attack patterns that force us to think strategically about which towers to bring into battle.
Over on PC, it’s a $8.99 premium game, whereas it’s free on Android, monetizing through an energy system, incentivized ads, and a few iAPs.
The good news here is that the incentivized ads don’t feel forced, and although the energy system isn’t super punishing, it can also be entirely removed through a $6.49 in-app purchase – so it’s still an easy recommendation for anyone interested in a slightly different tower defense game.
7) Arknights | Free - Landscape
Arknights mixes tower defense combat and strategy with team-based RPG elements to create a really unique gameplay experience that I enjoyed a lot more than I thought I would.
Part of what differentiates Arknight is that each tower is represented as a hero that has unique stats, attack patterns, and that can be upgraded in various ways, which adds a really deep min-maxing element to the gameplay.
The game is highly polished and has a distinct visual style, but also features a gacha unlocking system for acquiring new heroes, and an energy system for campaign missions. WITH that said, the game is really generous with its monetization system, which creates a great free-to-play experience that I think is definitely worth checking out even if you don’t typically like gacha mechanics.
8) Anomal Defenders | $4.99 - Landscape
Another well-designed tower defense game that definitely deserves a mention here is Anomaly Defenders, which as us play as an alien species defending their rocket launchpads from the humans attacking them.
The game stands out due to its unique enemies and deeply tactical gameplay where we’re even encouraged to pause the game every once in a while to strategize our next move.
It’s also really nice that we can freely switch between difficulties so we never get stuck on a level, and much like in Infinitode and Dungeon Warfare, we spend our time in-between levels on upgrading towers, acquiring new ones, and even unlocking new abilities that for example allow us to freeze the enemies.
9) Radiant Defense | Free - Landscape
Radiant Defense is a very challenging 15-level tower defense game that I found really fun because it lets us place walls on the map, so we can force the enemies down a specific path and get the most out of our towers.
With a few special buildings and nine towers that can be leveled up, the game feels like a very traditional tower defense game, but… then just much more challenging. And best of all, the entire game takes up only 14 MB of space, which means it can run on any phone.
Now, Radiant Defense is technically free to play, but it monetizes through 4 individual $1.99 iAPs that unlock new towers and buildings. And since these feel almost necessary to win the game, I’d consider it a premium $8 game, as that’s how you get the most out of it.
10) Random Dice + 33rd Random Defense| Free - Portrait
So, in Random Dice, we first select a deck of 5 dice towers to take with us into either real-time PvP, or co-op game modes.
During combat, we then spend mana gained by killing creatures on tapping a button that places a random tower from our deck on the playing field. We can also upgrade our towers using the same mana, and when two towers of the same dice end up being placed next to each other, we can even merge them to create a random upgraded tower.
At the same time, our opponent is doing the exact same thing, and every time we kill a creature on our playing field, it'll spawn as a monster on our opponent's side. And then we just continue like this until one player has lost 3 lives by letting 3 enemies slip by their defenses.
It’s a free game that monetizes through iAPs that let you progress faster, so I don’t recommend taking the game too seriously or expecting to beat the top players.
But as a casual game, there’s just something strangely addictive about the core gameplay loop that makes it almost impossible for me to not include it in this video.
And, if you like the idea of Random Dice, you might wanna check out 33rd Random Defense, which I actually think is even better because it also features a single-player mode.
