Solitaire Sweeper

Solitaire Sweeper - Minesweeper with cards

The pleasures of growing old: one gets to make minesweeper games without shame.

I made a small (and unpolished) Minesweeper variant. The game could be polished to make it more user friendly, but also I don’t know if I want to put too much more time into it. I was inspired by some of the Minesweepers Hempuli did.

Original idea was to make it work with a full deck of cards. Unfortunately 4 suits seemed like too much, so I dropped one. It was also an interesting experience to play around with the “single wrong click and you die” -mechanic. It seems somewhat under utilized way of designing puzzle games, cause usually as a designer you want the game to be forgiving.

Solitaire Sweeper – Release 1

Solitaire Sweeper - Minesweeper meets Solitaire Solitaire Sweeper - Minesweeper meets Solitaire Solitaire Sweeper - Minesweeper meets Solitaire


Windows: (0.1 Mb) (Release 1)

Minesweeper meets solitaire.

Your goal is to reveal all the cards without hitting any of the mines.

  • Click on space to reveal it
  • Right click to mark a mine

If you hit a mine, it’s game over.

If the card flashes, it means there’s a mine next to it in one of 8 neighboring spaces.

The number under the card tells you how many cards of the same suit are around that card. Max 8, min 0.

There are 3 suits (hearts, diamonds, clubs) and 13 cards each.

The orthogonal spaces next to a mine are always safe. I.e. Mines may NOT be next to each other horizontally nor vertically.

Hide No Seek

Hide No Seek - Single card social board game

I made a simple – maybe the simplest – board game! Its called Hide No Seek and it is available at the a print and play service The Game Crafter. Although if you want to play it you can also just print it out, or write the rules on a card with a sharpie.

The Game Crafter had a single card game design competition. You had to design a whole game with rules and everything on a single poker size playing card. I liked the challenge and ended up making a design I thought was rather obvious. As illustrated by this image of the card:

Hello! You found me! This is a GAME. And it is your turn. Hide this for someone else to find.

Noita – our roguelite in which every pixel is simulated – is coming to early access September 24th!

It has been a long and rewarding journey to get Noita to this point. I’m really excited to see people play the game. Even after working on Noita for way too many years, I still really enjoy playing the game. I think we have something special in our hands.

We do have a Steam page for our game. You can wishlist it there.

Nolla Games

It’s been a while since I’ve updated this blog. There’s a good reason for it: laziness. Also I’ve been working on a very secret game with Olli Harjola and Arvi Teikari. Olli is known for being the guy behind the puzzle platformer The Swapper. Arvi is better known as Hempuli and he has created a ton tiny games and also the awesome Environmental Station Alpha. It’s been great working with such talented people and we’re very close to announcing our game. But before that we have to announce our company: Nolla Games.

I know it’s not that exciting to read about a company announcement. The only humans that get excited about company announcements are telemarketers (and most of the are really just robots pretending to be humans). So to appease the actual humans who have read this far we offer this gif as token of our gratitude. The gif teases our upcoming game. It is recorded in the engine that is used by our still unannounced and completely mysterious game of mystery.

More about our mysterious game of mystery in a week. (I hope).

Also to celebrate the announcement of our new company, we (me, Olli and Arvi) will livestreaming on at 11 AM PST July 13, 2017. We will be playing a random selection of the over 100 games that they’ve created.
