Nations need to brace themselves for a complete loss of productivity as folks all over the world once again become immersed in the major time-suckage that is a bloons tower defense game. Enough talk, time to play Bloons Tower Defense 5!

Sumo wrestling, as everyone knows, is a noble and ancient Japanese art where a rotund man bounces around like a ping pong ball, occasionally careening into other sumo wrestlers, and shoveling rice down his gullet as quickly as possible to increase his size and convert all adversaries into clones of himself. So loosen your belt, grab your industrial-strength chopsticks, and jump into Hungry Sumo for seconds. Or tenths. Or fiftieths. Yum.

Combining classic card battling with RPG elements, Ninjakiwi's ambitious fantasy game provides a surprisingly engrossing experience. When you find yourself conscripted into service for a nearby town, you're less than thrilled at this seemingly dull turn of events. But of course destiny has a funny way of working things out. Complex and involving, with the promise of future multiplayer, Aetheron is a meaty experience for fans of the genre, and definitely something to keep your eye on.

It's the Bloons 2 Christmas Expansion Pack, a gift from Ninjakiwi. Take control once again of the dart-throwing monkey (now in jaunty Santa cap) and clear the bloons, now arranged in Christmas-themed patterns that will test your puzzling skills anew.

Bloons 2 is here and it continues the high standard of quality the series has established. It looks and sounds good, there's a lot of fun new stuff to experiment with and those who want a challenge will definitely find it here. This iteration introduces a bunch of new bloons, a world map and even some puzzle solving rewards. With 96 levels, Bloons 2 offers a lot of fun and heaps of challenge to keep you entertained for hours.

The Bloons Tower Defense games are some of the most popular ever featured on this site. Ninjakiwi has come up with an expansion pack that is fun, challenging, intriguing, frustrating (in places), and guaranteed to suck you right back into the world of the Bloons (just when you thought you were out). Will this tide us over until Bloons Tower Defense 5 comes out? Maybe, maybe not. But it's definitely worth checking out, if only for the amusement of finding the super secret surprise.

In this new puzzle-platformer from NinjaKiwi, isn't on the GameBoy; it just looks like it is (plus a few extra colours), and I probably would have enjoyed my childhood electronic entertainment a lot more if it had been. You play a nameless black figure, leaping from planet to planet, in your quest to... uh... leap from planet to planet.

Like being king of your castle? Best keep those orcish hordes at bay with a bit of fighting, building and training. But mostly fighting. After planting his castle on what might have been the resident sacred patch of land, a knight is facing wave after wave of orcs keen to remove him from the local scenery in Ninja Kiwi's interesting defense/hack-and-slash twist.

NinjaKiwi's follow-up to its first defense game is better in (almost) every way. Protect yourself from wave after wave of enemies by mixing potions and lobbing them across a wall. Each concoction will have a different affect, allowing you to mix and create your own recipes of doom.

NinjaKiwi's Bloons Tower Defense 4 is here at last, stepping over Bloons Tower Defense 3 and adding much more of everything we love! New units, new maps, better upgrades, and more evil bloons to pop! While some may complain about the addition of mochi coins, BTD4 can generate hours of fun without ever having to go near the purchasable content. So kick back, peel a banana, and begin the balloon popping fun!

Meeblings is a fun and quirky new action puzzle game from NinjaKiwi. If the title makes you think "Lemmings" then you're on the right track, but Meeblings is something different still. The objective is to get the target number of little Meeblings to any of the "Way Out" signs present in the level. Some levels have only one "way out", others have more.

Bloons Tower Defense 3 has finally been released after months of anticipation from all the hardcore Bloons fans out there. Picking up where Bloons TD 2 left off, the new game features even more tracks (eight in all!), new monkeys (towers) and upgraded gameplay mechanics.

A new action puzzle game from NinjaKiwi, Boombot is beautifully simple and well-executed. Your job, as some sort of evil omniscient explosives technician, is to maneuver an itty-bitty robot called Boombot to the exit of each level. Aside from the black bombs under your control, you'll have to manipulate TNT, oil drums, and explosive Senso-Gel to clear all fifty levels.

Ninja Kiwi have a sense for a great concept, and the courage to follow through on their own silly impulses. "Monkey Pops Balloons with Darts" is a fantastic tag line, and so is "Robot Smashes Pianos with Shovel". While most game-makers bend over backwards to create a consistent, recognizable environment (even when that environment is completely abstract), it's refreshing to play a game fueled by pure whimsy as you will see in Robomaro.

Do you like cake? Do you like double-decker cake? We are about to lay on you a triple-decker cake, with helium! When you eat this triple-decker cake, and then attempt to speak, your voice will sound squeaky and distorted. For lo, besoothe thee, from Ninja Kiwi comes the final installment of a trilogy that may well become a tetralogy if its popularity continues at this pace!

Hot on the heels of the original Bloons Tower Defense game comes a sequel that delivers more of the same explosive fun the original packed, and yet with 3 new difficulty levels and more tower types than ever before. Like the new Road Spikes that you can use to pop any remaining bloons if it looks like some will escape. And the update promises to provide a greater challenge than the first one did.

The latest from Bloons creators, Stephen Harris and Ninja Kiwi, Hotcorn is a game about popping corn... with heat. You control a smiling sun avatar with the mouse, moving it over kernels of corn on a top-down game board to pop them into some kind of exploded corn substance. Pop enough corn before time runs out and you win the level, simple as that.

Bloons Tower Defense takes the Bloons concept—popping balloons, preferably with monkeys involved—and spins it in a new and intriguing direction. It's your standard tower defense game but with monkeys popping balloons with darts and various other sharp instruments. It's a flawed but engaging title that is sure to please die-hard Bloons fans.

The latest offering from the folks down at NinjaKiwi. The objective is to protect yourself from a 30-round onslaught of enemies. Your chief weapons are flasks of potions that you lob at your enemies. You can control the potency of the weapon and the type of damage inflicted by altering the composition of your potion flask.

The popularity and success of Ninja Kiwi's recent Bloons game compelled the developer to put its next project on hold while they create another 50 levels to appease fans eager to pop More Bloons. But these levels promise to be even more difficult than the first batch.

There is something inherently gratifying about smashing or destroying something, even watching a building be demolished is good fun. So it should be no surprise that we see the concept come up a lot in games. Stephen over at Ninja Kiwi claims that his latest Flash game, "is based on the very simple fact that popping balloons is fun". And you know what? He's right! In Bloons you get to pop a lot of balloons!

Tabuto is a fast-paced action game with a strangely mesmerizing concept. Cards fall from the top of the screen, and your job is to touch them with the cursor before they vanish. The more you collect in a row, the more points you get, but if you drop 20 it's game over.
