About

Aligned with the the Queensland education curriculum but applicable Australia-wide, the object of the game is to be the longest snake! Do this by eating specific prey to add body parts and grow your snake. Avoid dangers like bull-dozers, cane toads, and invasive weeds, and refer to the accompanying information booklet for ecological details about every snake!

Indigenous
collaborations

We've partnered with Ben Williams (pic: on left), a Warlmanpa man based on Awabakal land, to produce all the artwork for our snake game. He has hand-painted all our snake heads, our background elements, and is currently working on the snake body card and tail card. 

​

We've also partnered with A/Prof Corey Tutt (Kamilaroi man) of Deadly Science for First Nations consultation for our snake game. In particular, Corey will assist with the names for each of our 18 snake species in the game. This is an extensive task, involving in-person yarning with elders from multiple mobs across Australia. Thanks, Corey!

Details

In Ssslap you take on 1 of 18 unique Australian venomous snakes competing to grow the longest in a resource-limited environment filled with dangers. Ssslap conveys several principles of biology, ecology, and conservation through its gameplay, specifically:

  • Biology

    • Featured snakes represent a diversity of venomous snakes found in Australia and its surrounding waters

    • Slapping mechanic embodies the ambush behavior of venomous snakes 

    • Preferred prey mechanic reflects the venom specificity of venomous snakes

  • Ecology

    • Winning hinges on gaining the most energy from food sources as a predator and converting it into body mass 

    • Prey and resource cards represent both biotic and abiotic factors influencing snake growth

    • Drought and rain cards illustrate the impact of environment on snakes (particularly the boom-bust rain cycle in Australia)

  • Conservation​

    • Invasive species cards demonstrate the cost of human-driven changes to the ecosystem

    • The bulldozer card illustrates the #1 conservation threat to snakes: habitat destruction (land-clearing).

 

The game comes with a bonus booklet full of fascinating evidence-based facts and stories about the snakes, written by Dr Zdenek, one of Australia’s leading experts.
